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

Previous research has demonstrated that the Reaching Married Adolescents intervention (RMA) was associated with changes in inequitable gender norms, intimate partner violence (IPV), and modern contraceptive use. This study seeks to understand if changes in inequitable gender norms mediate the RMA intervention's effects on contraceptive use and intimate partner violence (IPV). A 4-arm cluster randomized control trial was conducted to evaluate effects of the RMA intervention (household visits, small groups, combination, control) on married adolescent girls and their husbands in Dosso, Niger (baseline: 1042 dyads; 24 months follow-up: 737 dyads; 2016-2019). Mediation was assessed using inverse odds ratio weighting. In the small group intervention, of the total effect on IPV prevalence (8% reduction), indirect effects via inequitable gender norms are associated with a 2% decrease (95% CI, -0.07 to 0.12) and direct effects with a 6% decrease (95% CI, -0.20 to -0.02). For household visits, of the total effect on contraceptive use (20% increase), the indirect effect accounts for an 11% decrease (95% CI, -0.18 to -0.01) and direct effect, a 32% increase (95% CI, 0.13-0.44); this is similar to findings for the combination arm. This experimental evidence informs the value of changing underlying social norms to reduce IPV and increase contraception use.
