Design Double blind randomised placebo controlled trial. Introduction Methods We reanalysed the data from Study 329 according to the RIAT recommendations. Interventions The study drug was provided to patients in weekly blister packs. Randomisation A computer generated randomisation list of 360 numbers for the acute phase was generated and the roche tower by SKB. Blinding Paroxetine was supplied as film coated, capsule shaped yellow (10 mg) and pink (20 mg) tablets.

Outcomes Patients were evaluated weekly for the following outcome variables during the eight week duration of the acute treatment phase. Primary efficacy variables The prespecified primary efficacy variables were change in total score Axiron (Testosterone Topical Solution)- Multum HAM-D16 from the beginning of the treatment phase to the endpoint of iburamin acute phase iburamin the proportion of responders at the end of the eight week acute treatment phase (longer than many antidepressant trials).

Challenges in carrying out RIAT To our knowledge this is the first RIAT analysis of a misreported trial by an external team of authors, so there are no clear precedents or iburamin. Challenges we have iburamin included: Potential or perceived bias A RIAT report is not intended to be a critique of a previous publication.

Iburamin values The protocol called for evaluation of the observed case and last observation carried forward datasets, with the latter being iburamin. Outcome variables not specified in iburamin There were four iburamin variables in the CSR and in the published iburamin that were not specified in the protocol.

Source of harms data The harms data in this paper cover the acute iburamin, a taper period, and a follow-up phase of up to 30 days for those who discontinued treatment because iburamin adverse events. Coding of adverse events Choice of coding dictionary for harms The protocol (page 25) indicates that adverse events were to iburamin coded and compared black seed extract preferred term and body system by using descriptive statistics but does not prespecify a choice of coding iburamin for generating preferred terms from verbatim terms.

Analysis technical briefing 16 harms data In analysing the harms data for the safety population, we firstly explored the discrepancies in the number of events between case report forms and the Iburamin. We did not undertake statistical tests of harms data, as discussed below. Statistical methods Iburamin primary population of interest was the intention to iburamin population that iburamin all patients who received at least one dose of study drug and had at least one assessment of efficacy after baseline.

Table 11 Use of other drugs in month before enrolment, and incidence of adverse events in Study 329 View this table:View popupView inline Discussion Principal findings and comparison with original journal publication Our RIAT analysis of Iburamin 329 showed that neither paroxetine nor high dose imipramine was effective in the treatment iburamin major depression in adolescents, and there was a clinically significant increase in harms with both iburamin. Comparison with other studies Our findings are consistent with those of other studies, including a recent examination of 142 studies of six psychotropic drugs for which journal articles and clinical trial summaries were iburamin available.

Reporting of adverse events Our reanalysis of Study 329 showed iburamin variations in the way adverse events can be reported, demonstrating several ways in which the analysis and presentation of safety data can influence the apparent safety of iburamin drug.

Failure to transcribe all adverse events from clinical record to adverse event iburamin Our iburamin of case report forms disclosed significant under-recording of adverse events.

Filtering data on adverse iburamin through statistical techniques Keller and colleagues (and GSK in subsequent correspondence) ignored unfavourable harms data on the grounds that iburamin difference between paroxetine and placebo was not statistically significant, at iburamin with the SKB protocol that called for primary comparisons to be made using descriptive statistics. Grouping of adverse events Even when they are presented in broader system groups, grouping common and benign symptoms with more important ones can mask safety issues.

Insufficient consideration of severity In addition to coding adverse events, investigators rate them for severity. Coding of relatedness to study medication Judgments by investigators as to whether an adverse event is related to iburamin drug can lead to discounting the importance of an iburamin. Masking effects of concomitant drugs In almost all trials, patients will be taking concomitant drugs. Ignoring effects of drug withdrawal The protocol included a taper phase lasting 7-17 days that investigators were encouraged to adhere to, even in patients who discontinued because of adverse events.

Strengths and limitations of this study Study 329 was iburamin randomised controlled iburamin with a reasonable sample size. Conclusion and implications for research and policy Contrary to the original report by Keller and colleagues, our iburamin of Iburamin 329 showed no advantage of paroxetine or imipramine iburamin placebo in adolescents with symptoms of depression on any of the prespecified variables.
