Pre-pregnancy body mass index range and prevalence of hypertensive disorders of pregnancy: the Japan environment and children's study.
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. Not yet cited in PubMed.
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
backgroundNo consensus has been established for the optimal pre-pregnancy body mass index (BMI) required to reduce the incidence of hypertensive disorders of pregnancy (HDP) in Japanese women. This study investigated the association between the pre-pregnancy BMI range and the prevalence of HDP.
methodsData from 96,796 women with singleton pregnancies at ≥ 22 weeks of gestation from the Japan Environment and Children's Study (enrolled between 2011 and 2014)-a nationwide birth cohort study-were analyzed. The participants were categorized according to pre-pregnancy BMI, as follows: ≤ 16.00, 16.01-17.00, 17.01-18.00, 18.01-19.00, 19.01-20.00, 20.01-21.00, 21.01-22.00, 22.01-23.00, 23.01-24.00, 24.01-25.00, 25.01-26.00, 26.01-27.00, 27.01-28.00, 28.01-29.00, 29.01-30.00, and > 30.00 kg/m
resultsThe median pre-pregnancy BMI was 20.52 kg/m
conclusionsPre-pregnancy BMI > 22.00 kg/m
