1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

aimsTo describe and characterize the first cohort of Post-Authorization Safety Study (PASS) protocols reviewed under the recent European pharmacovigilance legislation.

methodsA systematic approach was used to compile all publicly available information on PASS protocols and assessments submitted from July 2012 to July 2015 from Pharmacovigilance Risk Assessment Committee (PRAC) minutes, European Medicines Agency (EMA) and European Network of Pharmacovigilance and Pharmacoepidemiology (ENCePP) webpages.

resultsDuring the study period, 189 different PASS protocols were submitted to the PRAC, half of which were entered in the ENCePP electronic register of post-authorization studies (EU-PAS) by July 2015. Those protocols were assessed during 353 PRAC reviews. The EMA published only 31% of the PRAC feedback, of which the main concerns were study design (37%) and feasibility (30%). Among the 189 PASS, slightly more involved primary data capture (58%). PASS assessing drug utilization mainly leveraged secondary data sources (58%). The majority of the PASS did not include a comparator (65%) and 35% of PASS also evaluated clinical effectiveness endpoints.

conclusionsTo the best of our knowledge this is the first comprehensive review of three years of PASS protocols submitted under the new pharmacovigilance legislation. Our results show that both EMA and PASS sponsors could respectively increase the availability of protocol assessments and documents in the EU-PAS. Protocol content review and the high number of PRAC comments related to methodological issues and feasibility concerns should raise awareness among PASS stakeholders to design more thoughtful studies according to pharmacoepidemiological principles and existing guidelines.
