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
objectiveMen who have sex with men (MSM) are disproportionately affected by HIV and represent the primary target population for pre-exposure prophylaxis (PrEP) use. However, PrEP adoption in China remains limited, partly due to its late regulatory approval. This study aims to investigate the awareness and willingness of PrEP use and associated factors among MSM in Maanshan city, so as to promote the popularization of PrEP.
methodsThis cross-sectional study was conducted in Maanshan City, China, between June 2016 and December 2019. Participants completed the questionnaire through respondent-driven sampling (RDS). The questionnaire information was organized and analyzed using SPSS 23.0 software. Both univariate and multivariate logistic regression models were employed to investigate the determinants of PrEP willingness and awareness among HIV-negative MSM.
resultsA total of 879 participants were enrolled, with 837 providing analyzable data. The majority (62.25%) were aged <30 years old, with 97.49% self-identified as homosexual. Among participants, 50.18% reported regular male sexual partners. Regarding sexual behaviors, 71.80% of MSM engaged in casual sex and 36.56% unprotected anal sex (UAI) within the last six months. HIV awareness was reported by 92.83% of respondents, while PrEP awareness was substantially lower (22.70%). Willingness to use PrEP was high (89.49%), with 16.49% preferring to take PrEP daily and 84.59% preferring to take PrEP on demand. Multivariate logistic regression revealed that vocational school (vs. high school or below), recent casual sex engagement, PrEP awareness, and recent UAI history were significant predictors of PrEP willingness. Higher education (university or above vs. high school or below), versatile sexual role (vs. op/insertive ones), recent casual sex and prior HIV testing were positively associated with PrEP awareness.
conclusionsMaanshan's MSM population demonstrated high PrEP acceptance but limited awareness. The findings suggest that expanding access to HIV testing could enhance PrEP awareness. Simultaneously, PrEP dissemination combined with targeted HIV prevention may effectively reduce HIV transmission in the MSM population.
