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

Understanding pre-exposure prophylaxis (PrEP) discontinuation is key to maximizing its effectiveness at the individual and population levels. Data came from the RADAR cohort study of MSM aged 16-29 years, 2015-2017. Participants included those who reported past 6-month PrEP use and discontinued its use by the interview date. Of the 197 participants who had used PrEP in the past 6 months, 65 discontinued use. Primary reasons for PrEP discontinuation included trouble getting to doctor's appointments (14, 21.5%) and issues related to insurance coverage or loss (13, 20.0%). Few (21%) who discontinued spoke to their doctor first, which has important implications for future long acting formulations.
