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

objectivesTo examine the combined influence of food environment, built environment, socio-economic status and individual factors (maternal age, parity, smoking status and need for an interpreter) on maternal overweight, gestational diabetes mellitus (GDM) and large-for-gestational age (LGA) births in Australia.

designRetrospective cohort study.

settingMelbourne, Australia. POPULATION: 163 760 singleton pregnancies/births. MAIN OUTCOMES MEASURES: Primary outcomes: maternal overweight, GDM and LGA births.

methodsStructural equation modelling (SEM) assessed direct and indirect associations, with maternal overweight as a mediator. LCA was used to classify risk variation across socio-economic strata.

resultsAmong 163 760 births, a higher density of unhealthy food outlets, lower liveability scores and greater socio-economic disadvantage were associated with maternal overweight. Maternal overweight strongly predicted GDM (c = 0.118, 95% CI: 0.113-0.124; p < 0.001) LGA births (c = 0.058, 95% CI: 0.053-0.059; p < 0.001), while higher liveability and walkability environments were protective against maternal overweight (c = -0.011, 95% CI: -0.019 to -0.002; p < 0.05). LCA identified a high-risk subgroup (85.1% overweight, 34.4% GDM) concentrated in socio-economically disadvantaged areas with poor access to healthy food and more walkable neighbourhoods.

conclusionsEnvironmental and socio-economic factors have significant independent influences on maternal overweight, GDM and LGA births. Addressing food access disparities, improving the walkability and liveability of residential areas and ensuring equitable healthcare infrastructure could reduce maternal health risks and promote better pregnancy outcomes.
