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

Sexual and gender minority (SGM) populations in India experience substantial psychosocial health burdens, which are likely patterned by intersecting axes of marginalized identities and positions within them. To characterize these intersectional inequalities and inform equitable intervention design, we investigated how psychosocial problems vary across combinations of SGM subgroup, sex work engagement, and socioeconomic status. We analyzed baseline data from the S3 Cohort Study of 799 men who have sex with men (MSM) and 630 transgender women in India. We employed intersectional Multilevel Analysis of Individual Heterogeneity and Discriminatory Accuracy (I-MAIHDA) using a Bayesian approach for six binary outcomes. Participants were nested within 16 social strata defined by SGM subgroup, sex work engagement, and socioeconomic status. We quantified between-stratum inequality (Variance Partition Coefficient, VPC), additive vs. interactive patterns (Proportional Change in Variance, PCV), and the discriminatory accuracy of intersectional strata in predicting outcomes (Area Under the Receiver Operating Characteristic Curve, AUC). All psychosocial problems were more prevalent among transgender women than MSM. Between-stratum inequality was strongest for depression (VPC = 9.0%; AUC = 0.66), followed by anxiety (VPC = 6.4%; AUC = 0.65), sexual violence victimization (VPC = 5.9%; AUC = 0.63), drug use (VPC = 5.5%; AUC = 0.62) and alcohol use (VPC = 4.7%; AUC = 0.62). For anxiety, problematic alcohol use, drug use, and sexual violence victimization, inequalities were driven predominantly by additive effects (PCV ∼ 62 to 96%). Depression showed primarily interactive effects (PCV = 43.5%; AUC = 0.66). Transgender women with indigenous identities who had low socioeconomic status and who engaged in sex work comprised the most marginalized stratum, with high adverse outcome prevalence. Health inequalities among SGM individuals are outcome-specific. Anxiety, problematic alcohol use, drug use and violence victimization outcomes follow cumulative disadvantage models with good discriminatory accuracy, while depression demonstrates interactive patterns, requiring targeted interventions.
