Associations between maternal body composition in the second trimester and premature rupture of membranes: a retrospective study using hospital information system data.
Article in BMC pregnancy and childbirth, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundMaternal nutrition is associated with premature rupture of membranes (PROM), which affects 6.7-10.0% of term pregnancies and poses significant health challenges for both mothers and children. However, the relationship between body composition, a detailed reflection of maternal nutrition, and PROM remains under-explored.
methodsWe conducted a retrospective correlational study using data from 38,610 obstetric cases (PROM = 9,857; non-PROM = 28,753) in the hospital information system of West China Second University Hospital. Multi-variable binary logistic regression was performed to investigate the relationships between key body composition indicators and PROM.
resultsAdvanced maternal age (OR:1.026, P < 0.001) and nulliparity (OR:1.402, P < 0.001) were associated with an increased risk of PROM, while longer gestational age (OR:0.864, P < 0.001) was linked to a lower risk. A higher waist-to-hip ratio was identified as a significant risk factor for PROM (OR:2.818, P < 0.001), whereas higher protein levels (OR:0.934, P < 0.001) and mineral content (OR:0.760, P = 0.045) were potential protective factors.
conclusionKey body composition indicators, including a higher waist-to-hip ratio, lower protein levels, and lower mineral content, are associated with an increased risk of PROM. Additionally, advanced maternal age, shorter gestational age, and nulliparity are linked to a higher incidence of PROM. These findings provide valuable insights for early PROM risk screening and contribute to maternal and child health promotion. Future prospective, longitudinal, and causal studies are necessary to validate and further support these findings.
