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

Background: HIV self-testing has been promoted globally as an effective complement to facility-based testing, particularly among men who have sex with men (MSM). However, evidence on HIV self-testing uptake and its determinants in western China remains limited. Objective: To assess the prevalence of HIV self-testing and identify associated factors among MSM in Chongqing, China. Methods: A cross-sectional study was conducted from March 2021 to March 2022 among MSM recruited using a snowball sampling strategy at CDC-based voluntary counseling and testing clinics in Chongqing. Participants completed an anonymous face-to-face questionnaire covering socio-demographic characteristics, HIV-related knowledge, sexual behaviors in the past 6 months, substance use, and HIV self-testing history. Multivariate logistic regression was used to identify factors associated with HIV self-testing. Results: A total of 2,315 MSM were included. Overall, 16.2% (374/2,315) reported ever using HIV self-testing kits, with blood-based tests accounting for 97.6% of use. Higher educational attainment (high school/vocational school: Conclusion: HIV self-testing uptake among MSM in Chongqing remains low. Education level, marital status, sexual behavior, and stimulant use were key correlates. These findings underscore the need to integrate HIV self-testing into existing HIV prevention services, with targeted strategies for MSM with lower educational attainment and those in stable partnerships.
