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
Background: Support from peers is a commonly employed behavioral prevention approach aimed at key populations to enhance HIV prevention efforts. Internet-based HIV self-testing (HIVST) has been widely used among men who have sex with men (MSM) across China over the past few years. Objective: We aimed to analyze the occurrence of Internet-based peer support and high-risk behaviors during the process of distributing HIVST kits among MSM. Methods: The single-arm prospective cohort study was conducted among MSM in Zhuhai, China. The study utilized an HIVST online ordering system based on WeChat, which was developed by Xutong. MSM who ordered HIVST kits and distributed them to people in their network for self-testing were defined as index participants. People who received the kits from the index participants and provided testing results were defined as alters. Chi-squared tests were used to compare baseline and follow-up characteristics of the participants. Cramer's V was used to quantify the level of association between the Internet-based HIVST and condomless anal sexual behaviors among index participants. Logistic regression analysis was used to evaluate factors associated with peer support among alter participants. A Results: A total of 288 index participants were included in the study, and they distributed HIVST kits to 478 alters. In the study, 84.0% (242/288) of the index participants reported that they provided peer support to their alters, and 87.4% (418/478) of the alters reported receiving peer support from the index participants. As for the alters, 19.9% (95/478) had sex with index participants on the day of HIVST. Among them, 24.2% (23/95) had sex after the HIVST and 72.6% (69/95) used a condom during sex. Index participants who had been asked for advice about HIV and other sexually transmitted infections were more likely to provide peer support to alters (OR: 1.85, 95% CI: 1.01-3.37). Conclusion: This study has enhanced our understanding of the occurrence of peer support and high-risk behaviors during the process of HIVST kits secondary distribution and provided evidence that Internet-based HIVST appears to be a promising approach for behaviors interventions among MSM.
