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

introductionWhile social capital can prevent diabetes, these benefits can be heterogeneous with respect to socioeconomic status. We investigated the association between social capital and gestational diabetes mellitus (GDM) while examining effect modification by household income. MATERIALS AND

methodsWe conducted a secondary data analysis using the Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study carried out between July 2013 and March 2017. Social capital (mutual aid, social trust, informal social control, collective action) and covariates were self-reported, while GDM diagnosis and other medical and physiological information were obtained from medical records. To assess the association between social capital and GDM, we conducted logistic regression models. We further tested for interactions between social capital and household income as well as stratified the models by income.

resultsAmong 20,339 study participants, 700 (3.4%) were diagnosed with GDM. Multivariable logistic regression models found that social trust and collective action were associated with lower GDM prevalence, even after adjustment of covariates. When stratifying household income, however, social capital was significantly associated with the reduced risks of GDM only among participants with higher household income (OR: 0.90, 95% CI: 0.85-0.97). No significant association was observed among those with lower household income.

conclusionsThe health benefit of social capital on GDM prevalence was heterogeneous, and the protective effect of social capital on GDM was found only among women with higher household income. The differential impact of social capital on GDM highlights the need for targeted interventions addressing structural health inequities.
