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
introductionOne of the challenges of a national HIV pre-exposure prophylaxis (PrEP) program is continuation of PrEP use and retention in care. The aim of this study was to explore determinants of loss to follow-up (LTFU) among men who have sex with men (MSM) in the Dutch national PrEP pilot program.
methodsData from the national STI surveillance database between July 1, 2019, and December 31, 2022, were used of all 3-monthly PrEP pilot consultations among MSM who had at least 2 consultations. LTFU was defined as having no consultation for ≥7 months, and was further divided into "missed consultation/restarted" and "definitive LTFU." We used mutually adjusted, multivariable, multistate, time-homogenous Markov models to analyze demographic and behavioral associations with LTFU.
resultsA total of 8948 participants (62,158 consultations) were included, of which 30% were LTFU at some point. Young participants and on-demand/nonrecent PrEP users (ie, in the past 3 months) were more likely to become LTFU. Participants who had ≥6 partners (vs 0-2) in the past 6 months or were ≥25 years of age (vs <25) were less likely to become LTFU. In addition, non-Dutch origin was associated with missed consultation/restarted and definitive LTFU. Furthermore, having had no (condomless) anal sex in the past 6 months was associated with missed consultation/restarted.
conclusionsSpecific characteristics of MSM who were LTFU, such as young age, non-Dutch origin, and on-demand PrEP use, may be used to implement targeted interventions to increase PrEP retention and possibly prevent new HIV infections among PrEP users.
