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

This brief report presents findings on informal, non-prescribed PrEP use among an online sample of gay, bisexual and other men who have sex with men (n = 196). Mean age was 33.4. Participants were Hispanic (13.3%), African American (15.8%), white (63.8%), and other race/ethnicity (6.6%). Informal PrEP users (11%) more frequently reported past year sexually transmitted infections (p < 0.001), group sex (p < 0.001), sex in public (p < 0.01), transactional sex (p < 0.001), ever receiving a formal PrEP prescription (p < 0.05), and ease of finding diverted HIV medications on gay dating/sex apps (p < 0.05). Formal PrEP uptake should be encouraged to mitigate potential negative consequences of informal use.
