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.
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
BackgroundIn an outbreak of hepatitis A among men who have sex with men (MSM) in Berlin (2016 and 2017), patients frequently reported anonymous sex and use of dating applications to meet sexual contacts, hampering tracing and vaccination of contacts.AimOur objective was to evaluate dating apps and websites as a means of spreading prevention messages among MSM during the ongoing outbreak.MethodsAdvertisements in different formats were placed on three MSM dating apps and eight websites for anonymous dating during three weeks in March and April 2017. We calculated frequency of ads shown and click-through rates (CTR) and investigated the independent effect of format and platform on the number of clicks using a negative binomial regression model. We evaluated the campaign's impact using a survey among visitors of a large gay-lesbian street-festival in Berlin.ResultsOverall, 1,920,180 ads were shown and clicked on 8,831 times (CTR = 0.46%). The multivariable model showed significantly more clicks on one dating app (incidence rate ratio (IRR) = 9.5; 95% confidence interval (CI): 7.7-12.2) than on websites and on full-screen ads (IRR = 3.1; 95% CI: 2.5-3.8) than on banner ads. Of 266 MSM who participated in the survey, 190 (71%) knew about the outbreak and 39 (15%) declared to have been vaccinated recently because of the campaign.ConclusionsDating apps provided a means to rapidly reach and influence a substantial number of MSM in Berlin and should complement case-based contact tracing among MSM in outbreak settings. Clicking on ads depended on platform and format used.
