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
Introduction: This study investigated the mechanisms underlying mental health risks among lesbian/gay (LG) and bisexual university students in China, focusing on the roles of sexual identity centrality, identity uncertainty, and interpersonal discrimination in depressive symptoms. Methods: A cross-sectional survey was conducted with 363 university students (142 LG students and 221 bisexual). Group differences were examined, and structural equation modeling was used to test the direct and indirect associations among sexual orientation, sexual identity centrality, identity uncertainty, interpersonal discrimination, and depressive symptoms. Results: Compared with LG participants, bisexual participants reported lower identity centrality, higher identity uncertainty, and fewer experiences of interpersonal discrimination, whereas no significant group difference was found in depressive symptoms. Structural equation modeling indicated that identity uncertainty and interpersonal discrimination jointly mediated the association between bisexuality and depressive symptoms, with the two indirect effects operating in opposite directions and forming a competing mediation effect. Sexual identity centrality showed a double-edged role: it was associated with lower identity uncertainty but greater interpersonal discrimination, which in turn were differentially associated with depressive symptoms. Discussion: These findings reveal complex and divergent mechanisms linking sexual orientation and mental health among Chinese sexual minority university students. They also suggest that clinical interventions and future research should attend to both intrapersonal identity-related processes and interpersonal minority stress experiences when addressing depressive symptoms among LGB young adults.
