Effectiveness of non-steroidal anti-inflammatory drugs for the treatment of pain in knee and hip osteoarthritis: a network meta-analysis.

BACKGROUND Non-steroidal anti-inflammatory drugs (NSAIDs) are the backbone of osteoarthritis pain management. We aimed to assess the effectiveness of different preparations and doses of NSAIDs on osteoarthritis pain in a network meta-analysis. METHODS For this network meta-analysis, we considered randomised trials comparing any of the following interventions: NSAIDs, paracetamol, or placebo, for the treatment of osteoarthritis pain. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) and the reference lists of relevant articles for trials published between Jan 1, 1980, and Feb 24, 2015, with at least 100 patients per group. The prespecified primary and secondary outcomes were pain and physical function, and were extracted in duplicate for up to seven timepoints after the start of treatment. We used an extension of multivariable Bayesian random effects models for mixed multiple treatment comparisons with a random effect at the level of trials. For the primary analysis, a random walk of first order was used to account for multiple follow-up outcome data within a trial. Preparations that used different total daily dose were considered separately in the analysis. To assess a potential dose-response relation, we used preparation-specific covariates assuming linearity on log relative dose. FINDINGS We identified 8973 manuscripts from our search, of which 74 randomised trials with a total of 58���556 patients were included in this analysis. 23 nodes concerning seven different NSAIDs or paracetamol with specific daily dose of administration or placebo were considered. All preparations, irrespective of dose, improved point estimates of pain symptoms when compared with placebo. For six interventions (diclofenac 150 mg/day, etoricoxib 30 mg/day, 60 mg/day, and 90 mg/day, and rofecoxib 25 mg/day and 50 mg/day), the probability that the difference to placebo is at or below a prespecified minimum clinically important effect for pain reduction (effect size [ES] -0��37) was at least 95%. Among maximally approved daily doses, diclofenac 150 mg/day (ES -0��57, 95% credibility interval [CrI] -0��69 to -0��46) and etoricoxib 60 mg/day (ES -0��58, -0��73 to -0��43) had the highest probability to be the best intervention, both with 100% probability to reach the minimum clinically important difference. Treatment effects increased as drug dose increased, but corresponding tests for a linear dose effect were significant only for celecoxib (p=0��030), diclofenac (p=0��031), and naproxen (p=0��026). We found no evidence that treatment effects varied over the duration of treatment. Model fit was good, and between-trial heterogeneity and inconsistency were low in all analyses. All trials were deemed to have a low risk of bias for blinding of patients. Effect estimates did not change in sensitivity analyses with two additional statistical models and accounting for methodological quality criteria in meta-regression analysis. INTERPRETATION On the basis of the available data, we see no role for single-agent paracetamol for the treatment of patients with osteoarthritis irrespective of dose. We provide sound evidence that diclofenac 150 mg/day is the most effective NSAID available at present, in terms of improving both pain and function. Nevertheless, in view of the safety profile of these drugs, physicians need to consider our results together with all known safety information when selecting the preparation and dose for individual patients.

Tocilizumab for induction and maintenance of remission in giant cell arteritis: a phase 2, randomised, double-blind, placebo-controlled trial.

BACKGROUND Giant cell arteritis is an immune-mediated disease of medium and large-sized arteries that affects mostly people older than 50 years of age. Treatment with glucocorticoids is the gold-standard and prevents severe vascular complications but is associated with substantial morbidity and mortality. Tocilizumab, a humanised monoclonal antibody against the interleukin-6 receptor, has been associated with rapid induction and maintenance of remission in patients with giant cell arteritis. We therefore aimed to study the efficacy and safety of tocilizumab in the first randomised clinical trial in patients with newly diagnosed or recurrent giant cell arteritis. METHODS In this single centre, phase 2, randomised, double-blind, placebo-controlled trial, we recruited patients aged 50 years and older from University Hospital Bern, Switzerland, who met the 1990 American College of Rheumatology criteria for giant cell arteritis. Patients with new-onset or relapsing disease were randomly assigned (2:1) to receive either tocilizumab (8 mg/kg) or placebo intravenously. 13 infusions were given in 4 week intervals until week 52. Both groups received oral prednisolone, starting at 1 mg/kg per day and tapered down to 0 mg according to a standard reduction scheme defined in the study protocol. Allocation to treatment groups was done using a central computerised randomisation procedure with a permuted block design and a block size of three, and concealed using central randomisation generated by the clinical trials unit. Patients, investigators, and study personnel were masked to treatment assignment. The primary outcome was the proportion of patients who achieved complete remission of disease at a prednisolone dose of 0��1 mg/kg per day at week 12. All analyses were intention to treat. This trial is registered with ClinicalTrials.gov, number NCT01450137. RESULTS Between March 3, 2012, and Sept 9, 2014, 20 patients were randomly assigned to receive tocilizumab and prednisolone, and ten patients to receive placebo and glucocorticoid; 16 (80%) and seven (70%) patients, respectively, had new-onset giant cell arteritis. 17 (85%) of 20 patients given tocilizumab and four (40%) of ten patients given placebo reached complete remission by week 12 (risk difference 45%, 95% CI 11-79; p=0��0301). Relapse-free survival was achieved in 17 (85%) patients in the tocilizumab group and two (20%) in the placebo group by week 52 (risk difference 65%, 95% CI 36-94; p=0��0010). The mean survival-time difference to stop glucocorticoids was 12 weeks in favour of tocilizumab (95% CI 7-17; p<0��0001), leading to a cumulative prednisolone dose of 43 mg/kg in the tocilizumab group versus 110 mg/kg in the placebo group (p=0��0005) after 52 weeks. Seven (35%) patients in the tocilizumab group and five (50%) in the placebo group had serious adverse events. INTERPRETATION Our findings show, for the first time in a trial setting, the efficacy of tocilizumab in the induction and maintenance of remission in patients with giant cell arteritis.

Preferences for the organization of long-term follow-up in adolescent and young adult cancer survivors.

PURPOSE As survival rates of adolescent and young adult (AYA) cancer patients increase, a growing number of AYA cancer survivors need follow-up care. However, there is little research on their preferences for follow-up care. We aimed to (1) describe AYA cancer survivors' preferences for the organization and content of follow-up care, (2) describe their preferences for different models of follow-up, and (3) investigate clinical and sociodemographic characteristics associated with preferences for the different models. METHODS AYA cancer survivors (diagnosed with cancer at age 16-25��years; ���5��years after diagnosis) were identified through the Cancer Registry Zurich and Zug. Survivors completed a questionnaire on follow-up attendance, preferences for organizational aspects of follow-up care (what is important during follow-up, what should be included during appointments, what specialists should be involved, location), models of follow-up (telephone/questionnaire, general practitioner (GP), pediatric oncologist, medical oncologist, multidisciplinary team), and sociodemographic characteristics. Information on tumor and treatment was available through the Cancer Registry Zurich and Zug. RESULTS Of 389 contacted survivors, 160 (41.1��%) participated and 92 (57.5��%) reported still attending follow-up. Medical aspects of follow-up care were more important than general aspects (p��<��0.001). Among different organizational models, follow-up by a medical oncologist was rated higher than all other models (p��=��0.002). Non-attenders of follow-up rated GP-led follow-up significantly higher than attenders (p��=��0.001). CONCLUSION Swiss AYA cancer survivors valued medical content of follow-up and showed a preference for medical oncologist-led follow-up. Implementation of different models of follow-up care might improve accessibility and attendance among AYA cancer survivors.

Absence of Hepatitis Delta Infection in a Large Rural HIV Cohort in Tanzania

OBJECTIVES The epidemiological and clinical determinants of hepatitis delta virus (HDV) infection in sub-Saharan Africa are ill-defined. We determined the prevalence of HDV infection in HIV/hepatitis B virus (HBV)-co-infected individuals in rural Tanzania. DESIGN AND METHODS We screened all hepatitis B virus (HBV)-infected adults under active follow-up in the Kilombero and Ulanga Antiretroviral Cohort (KIULARCO) for anti-HDV antibodies. In positive samples, we performed a second serological test and nucleic acid amplification. Demographic and clinical characteristics at initiation of antiretroviral therapy (ART) were compared between anti-HDV-negative and positive patients. RESULTS Among 222 HIV/HBV-coinfected patients on ART, 219 (98.6%) had a stored serum sample available and were included. Median age was 37 years, 55% were female, 46% had WHO stage III/IV HIV disease and median CD4 count was 179 cells/��L. The prevalence of anti-HDV positivity was 5.0% (95% confidence interval 2.8%-8.9%). There was no significant predictor of anti-HDV positivity. HDV could not be amplified in any of the anti-HDV-positive patients and the second serological test was negative in all of them. CONCLUSIONS We found no confirmed case of HDV infection among over 200 HIV/HBV-co-infected patients in Tanzania. As false-positive serology results are common, screening results should be confirmed with a second test.

Islam und Muslime im Kontext deutschschweizerischer ��ffentlichkeit

This study tries to assess the status of Islam in the context of the Swiss discursive public sphere. Relying on an empirical survey conducted with representatives from fifty Muslim organisations based in the German-speaking part of Switzerland, the study examines the relative position of Muslim organisations in the political public sphere and the role of Islam in public debate from the perspective of the organisations themselves. The empirical findings will be interpreted using two ideal types. The category ���public sphere��� known from Ju��rgen Habermas��� works will help to determine the social status of the Muslim community in the context of the Swiss public sphere, while the normative concept ���public religion���, as developed by the sociologist Jose�� Casanova in his book Public Religions in the Modern World, will contribute to determine the role of Islam in Swiss public debate.

Primitive ontology and quantum state in the GRW matter density theory

The paper explains in what sense the GRW matter density theory (GRWm) is a primitive ontology theory of quantum mechanics and why, thus conceived, the standard objections against the GRW formalism do not apply to GRWm. We consider the different options for conceiving the quantum state in GRWm and argue that dispositionalism is the most attractive one.

Ultrathin Strut Biodegradable Polymer Sirolimus-Eluting Stent Versus Durable-Polymer Everolimus-Eluting Stent for Percutaneous Coronary Revascularization: 2-Year Results of the BIOSCIENCE Trial.

BACKGROUND No data are available on the long-term performance of ultrathin strut biodegradable polymer sirolimus-eluting stents (BP-SES). We reported 2-year clinical outcomes of the BIOSCIENCE (Ultrathin Strut Biodegradable Polymer Sirolimus-Eluting Stent Versus Durable Polymer Everolimus-Eluting Stent for Percutaneous Coronary Revascularisation) trial, which compared BP-SES with durable-polymer everolimus-eluting stents (DP-EES) in patients undergoing percutaneous coronary intervention. METHODS AND RESULTS A total of 2119 patients with minimal exclusion criteria were assigned to treatment with BP-SES (n=1063) or DP-EES (n=1056). Follow-up at 2��years was available for 2048 patients (97%). The primary end point was target-lesion failure, a composite of cardiac death, target-vessel myocardial infarction, or clinically indicated target-lesion revascularization. At 2��years, target-lesion failure occurred in 107 patients (10.5%) in the BP-SES arm and 107 patients (10.4%) in the DP-EES arm (risk ratio [RR] 1.00, 95% CI 0.77-1.31, P=0.979). There were no significant differences between BP-SES and DP-EES with respect to cardiac death (RR 1.01, 95% CI 0.62-1.63, P=0.984), target-vessel myocardial infarction (RR 0.91, 95% CI 0.60-1.39, P=0.669), target-lesion revascularization (RR 1.17, 95% CI 0.81-1.71, P=0.403), and definite stent thrombosis (RR 1.38, 95% CI 0.56-3.44, P=0.485). There were 2 cases (0.2%) of definite very late stent thrombosis in the BP-SES arm and 4 cases (0.4%) in the DP-EES arm (P=0.423). In the prespecified subgroup of patients with ST-segment elevation myocardial infarction, BP-SES was associated with a lower risk of target-lesion failure compared with DP-EES (RR 0.48, 95% CI 0.23-0.99, P=0.043, Pinteraction=0.026). CONCLUSIONS Comparable safety and efficacy profiles of BP-SES and DP-EES were maintained throughout 2��years of follow-up. CLINICAL TRIAL REGISTRATION URL: https://www.clinicaltrials.gov.

Tuberculosis in Cape Town: An age-structured transmission model.

BACKGROUND Tuberculosis (TB) is the leading cause of death in South Africa. The burden of disease varies by age, with peaks in TB notification rates in the HIV-negative population at ages 0-5, 20-24, and 45-49 years. There is little variation between age groups in the rates in the HIV-positive population. The drivers of this age pattern remain unknown. METHODS We developed an age-structured simulation model of Mycobacterium tuberculosis (Mtb) transmission in Cape Town, South Africa. We considered five states of TB progression: susceptible, infected (latent TB), active TB, treated TB, and treatment default. Latently infected individuals could be re-infected; a previous Mtb infection slowed progression to active disease. We further considered three states of HIV progression: HIV negative, HIV positive, on antiretroviral therapy. To parameterize the model, we analysed treatment outcomes from the Cape Town electronic TB register, social mixing patterns from a Cape Town community and used literature estimates for other parameters. To investigate the main drivers behind the age patterns, we conducted sensitivity analyses on all parameters related to the age structure. RESULTS The model replicated the age patterns in HIV-negative TB notification rates of Cape Town in 2009. Simulated TB notification rate in HIV-negative patients was 1000/100,000 person-years (pyrs) in children aged <5 years and decreased to 51/100,000 in children 5-15 years. The peak in early adulthood occurred at 25-29 years (463/100,000 pyrs). After a subsequent decline, simulated TB notification rates gradually increased from the age of 30 years. Sensitivity analyses showed that the dip after the early adult peak was due to the protective effect of latent TB and that retreatment TB was mainly responsible for the rise in TB notification rates from the age of 30 years. CONCLUSION The protective effect of a first latent infection on subsequent infections and the faster progression in previously treated patients are the key determinants of the age-structure of TB notification rates in Cape Town.

Hepatitis B Infection, Viral Load and Resistance in HIV-Infected Patients in Mozambique and Zambia.

BACKGROUND Few data on the virological determinants of hepatitis B virus (HBV) infection are available from southern Africa. METHODS We enrolled consecutive HIV-infected adult patients initiating antiretroviral therapy (ART) at two urban clinics in Zambia and four rural clinics in Northern Mozambique between May 2013 and August 2014. HBsAg screening was performed using the Determine�� rapid test. Quantitative real-time PCR and HBV sequencing were performed in HBsAg-positive patients. Risk factors for HBV infection were evaluated using Chi-square and Mann-Whitney tests and associations between baseline characteristics and high level HBV replication explored in multivariable logistic regression. RESULTS Seventy-eight of 1,032 participants in Mozambique (7.6%, 95% confidence interval [CI]: 6.1-9.3) and 90 of 797 in Zambia (11.3%, 95% CI: 9.3-13.4) were HBsAg-positive. HBsAg-positive individuals were less likely to be female compared to HBsAg-negative ones (52.3% vs. 66.1%, p<0.001). Among 156 (92.9%) HBsAg-positive patients with an available measurement, median HBV viral load was 13,645 IU/mL (interquartile range: 192-8,617,488 IU/mL) and 77 (49.4%) had high values (>20,000 UI/mL). HBsAg-positive individuals had higher levels of ALT and AST compared to HBsAg-negative ones (both p<0.001). In multivariable analyses, male sex (adjusted odds ratio: 2.59, 95% CI: 1.22-5.53) and CD4 cell count below 200/��l (2.58, 1.20-5.54) were associated with high HBV DNA. HBV genotypes A1 (58.8%) and E (38.2%) were most prevalent. Four patients had probable resistance to lamivudine and/or entecavir. CONCLUSION One half of HBsAg-positive patients demonstrated high HBV viremia, supporting the early initiation of tenofovir-containing ART in HIV/HBV-coinfected adults.

Absence of Active Hepatitis C Virus Infection in Human Immunodeficiency Virus Clinics in Zambia and Mozambique.

Few studies have evaluated the prevalence of replicating hepatitis C virus (HCV) infection in sub-Saharan Africa. Among 1812 individuals infected with human immunodeficiency virus, no patient in rural Mozambique and 4 patients in urban Zambia were positive for anti-HCV antibodies. Of these, none had confirmed HCV replication.

The winner takes it all? Characteristics of adolescents at-risk/problem gamblers in Switzerland

Background: Gambling has and still entertains people in almost all societies throughout the world. Western societies have faced considerable changes in the amount and accessibility of gambling possibilities during the last decades, and the rates of both adolescent gamblers and problem gamblers have increased significantly. Objective: To determine the characteristics of at-risk and problem adolescent gamblers in Switzerland. Subjects: The study population consisted of 3134 students (1669 females) attending post-mandatory education in 15 randomly chosen centres. Participants were divided into non- (n=2207), non-problematic (n=754) and at-risk/ problematic gamblers (n=176). Methods: Both gambling groups were compared to non-gamblers on socio-demographic measures, substance use and Internet use. Overall, 29.6% had gambled during the past year and 5.6% had gambled in a risky or problematic way. Compared to non-gamblers and after controlling for potential confounders, non-problem gamblers were significantly more likely to be male, apprentices and to misuse alcohol. At-risk/problematic gamblers were additionally more likely to smoke cannabis, to be problematic Internet users and to be non-Swiss than non-gamblers. Conclusion: At-risk and problematic adolescent gambling is associated with other health risk behaviours. Health practitioners should include gambling in the psycho-social screening and preventive counselling of adolescents.

[Health Status of Young Men in Switzerland: Monitoring Results from Conscription].

Abstract Due to their representativeness and consistent measurement standards the medical und sports data of the Swiss conscripts provide a valuable basis for a continuous health monitoring of young Swiss men. During three to four years, the prevalence of overweight and obesity seems to stabilise on a high level. After a longer period of decreasing performance at the endurance test between the 1980s and 2002, the level of physical performance in the fitness test does no longer decrease since 2006. However, health and health behaviour show significant regional and socioeconomic inequalities among young Swiss men. Besides economic resources and education, major driving factors behind these inequalities can be identified in health knowledge, values, and attitudes.

Kulturkapital und Gesundheitskompetenz junger Erwachsener

Hintergrund: Empirisch l��sst sich zunehmend belegen, dass Gesundheitskompetenz in der Bev��lkerung sozial ungleich verteilt ist. Es ist jedoch noch wenig erforscht, wie sozio-��konomische Faktoren diese Ungleichverteilung der Gesundheitskompetenz beeinflussen. Bourdieu's Kapitaltheorie bietet einen bedeutsamen theoretischen Rahmen, um Gesundheitskompetenz soziologisch zu ergr��nden. In unserer Studie untersuchen wir den Einfluss verschiedener Kulturkapitalien auf die Gesundheitskompetenz junger Erwachsener unter der Kontrolle ��konomischer Ressourcen. Methoden: Datengrundlage war das 2010 ��� 2011 durchgef��hrte Eidgen��ssische Jugendsurvey ��� eine alle zwei Jahre durchgef��hrte Befragung junger Stellungspflichtiger sowie einer zus��tzlichen Stichprobe unter jungen Frauen in der Schweiz. Der Datensatz umfasste insgesamt 10014 junge Schweizer und Schweizerinnen aus allen Schweizer Sprachregionen und sozialen Klassen. Aus acht Variablen zur Messung der Gesundheitskompetenz (funktionale, interaktive und kritische Gesundheitskompetenz) bildeten wir einen Summenscore. Wir ber��cksichtigten folgende Messkonzepte von Kulturkapital: Bildungsklasse (institutionalisiertes Kulturkapital), gesundheitsbezogene individuelle und famili��re Werthaltungen (inkorporiertes Kulturkapital) sowie die Anzahl von B��chern im Haushalt (objektiviertes Kulturkapital). Anhand von multiplen linearen Regressionen testeten wir den Einfluss kulturellen Kapitals auf den Summenscore unter der Kontrolle ��konomischen Kapitals. Ergebnisse: Unter der Kontrolle ��konomischer Faktoren hatten alle Formen des Kulturkapitals einen signifikanten Einfluss auf den Gesundheitskompetenzwert. Die kulturellen Faktoren erkl��rten mehr Varianz in dem Summenscore als die ��konomischen Faktoren. Junge Erwachsene mit (-) sehr gro��em/ziemlich gro��em Interesse an Gesundheit, (-) deren Eltern mehr als 200 B��cher besa��en, (-) die einen gesunden Lebensstil als sehr wichtig erachteten (in der Familie oder f��r sich selbst) oder (-) einen h��heren Bildungszweig besuchten, hatten einen h��heren Wert auf dem Summenscore der Gesundheitskompetenz. Diskussion: Alle drei Formen des Kulturkapitals trugen signifikant zur Erkl��rung der ungleichen Verteilung von Gesundheitskompetenz bei. Um die sozialen Prozesse, die dieser Ungleichverteilung zugrunde liegen noch besser zu verstehen, sollte kulturelles Kapital nicht auf einen Bildungsindikator beschr��nkt werden. Objektivierte und inkorporierte Aspekte kulturellen Kapitals sollten die entsprechenden Messkonzepte erg��nzen.

Psychological therapies for panic disorder with or without agoraphobia in adults: a network meta-analysis.

BACKGROUND Panic disorder is characterised by the presence of recurrent unexpected panic attacks, discrete periods of fear or anxiety that have a rapid onset and include symptoms such as racing heart, chest pain, sweating and shaking. Panic disorder is common in the general population, with a lifetime prevalence of 1% to 4%. A previous Cochrane meta-analysis suggested that psychological therapy (either alone or combined with pharmacotherapy) can be chosen as a first-line treatment for panic disorder with or without agoraphobia. However, it is not yet clear whether certain psychological therapies can be considered superior to others. In order to answer this question, in this review we performed a network meta-analysis (NMA), in which we compared eight different forms of psychological therapy and three forms of a control condition. OBJECTIVES To assess the comparative efficacy and acceptability of different psychological therapies and different control conditions for panic disorder, with or without agoraphobia, in adults. SEARCH METHODS We conducted the main searches in the CCDANCTR electronic databases (studies and references registers), all years to 16 March 2015. We conducted complementary searches in PubMed and trials registries. Supplementary searches included reference lists of included studies, citation indexes, personal communication to the authors of all included studies and grey literature searches in OpenSIGLE. We applied no restrictions on date, language or publication status. SELECTION CRITERIA We included all relevant randomised controlled trials (RCTs) focusing on adults with a formal diagnosis of panic disorder with or without agoraphobia. We considered the following psychological therapies: psychoeducation (PE), supportive psychotherapy (SP), physiological therapies (PT), behaviour therapy (BT), cognitive therapy (CT), cognitive behaviour therapy (CBT), third-wave CBT (3W) and psychodynamic therapies (PD). We included both individual and group formats. Therapies had to be administered face-to-face. The comparator interventions considered for this review were: no treatment (NT), wait list (WL) and attention/psychological placebo (APP). For this review we considered four short-term (ST) outcomes (ST-remission, ST-response, ST-dropouts, ST-improvement on a continuous scale) and one long-term (LT) outcome (LT-remission/response). DATA COLLECTION AND ANALYSIS As a first step, we conducted a systematic search of all relevant papers according to the inclusion criteria. For each outcome, we then constructed a treatment network in order to clarify the extent to which each type of therapy and each comparison had been investigated in the available literature. Then, for each available comparison, we conducted a random-effects meta-analysis. Subsequently, we performed a network meta-analysis in order to synthesise the available direct evidence with indirect evidence, and to obtain an overall effect size estimate for each possible pair of therapies in the network. Finally, we calculated a probabilistic ranking of the different psychological therapies and control conditions for each outcome. MAIN RESULTS We identified 1432 references; after screening, we included 60 studies in the final qualitative analyses. Among these, 54 (including 3021 patients) were also included in the quantitative analyses. With respect to the analyses for the first of our primary outcomes, (short-term remission), the most studied of the included psychological therapies was CBT (32 studies), followed by BT (12 studies), PT (10 studies), CT (three studies), SP (three studies) and PD (two studies).The quality of the evidence for the entire network was found to be low for all outcomes. The quality of the evidence for CBT vs NT, CBT vs SP and CBT vs PD was low to very low, depending on the outcome. The majority of the included studies were at unclear risk of bias with regard to the randomisation process. We found almost half of the included studies to be at high risk of attrition bias and detection bias. We also found selective outcome reporting bias to be present and we strongly suspected publication bias. Finally, we found almost half of the included studies to be at high risk of researcher allegiance bias.Overall the networks appeared to be well connected, but were generally underpowered to detect any important disagreement between direct and indirect evidence. The results showed the superiority of psychological therapies over the WL condition, although this finding was amplified by evident small study effects (SSE). The NMAs for ST-remission, ST-response and ST-improvement on a continuous scale showed well-replicated evidence in favour of CBT, as well as some sparse but relevant evidence in favour of PD and SP, over other therapies. In terms of ST-dropouts, PD and 3W showed better tolerability over other psychological therapies in the short term. In the long term, CBT and PD showed the highest level of remission/response, suggesting that the effects of these two treatments may be more stable with respect to other psychological therapies. However, all the mentioned differences among active treatments must be interpreted while taking into account that in most cases the effect sizes were small and/or results were imprecise. AUTHORS' CONCLUSIONS There is no high-quality, unequivocal evidence to support one psychological therapy over the others for the treatment of panic disorder with or without agoraphobia in adults. However, the results show that CBT - the most extensively studied among the included psychological therapies - was often superior to other therapies, although the effect size was small and the level of precision was often insufficient or clinically irrelevant. In the only two studies available that explored PD, this treatment showed promising results, although further research is needed in order to better explore the relative efficacy of PD with respect to CBT. Furthermore, PD appeared to be the best tolerated (in terms of ST-dropouts) among psychological treatments. Unexpectedly, we found some evidence in support of the possible viability of non-specific supportive psychotherapy for the treatment of panic disorder; however, the results concerning SP should be interpreted cautiously because of the sparsity of evidence regarding this treatment and, as in the case of PD, further research is needed to explore this issue. Behaviour therapy did not appear to be a valid alternative to CBT as a first-line treatment for patients with panic disorder with or without agoraphobia.
