[Impact of pre-pregnancy body mass index on maternal and infant outcomes in twin pregnancies].
Article in Zhongguo dang dai er ke za zhi = Chinese journal of contemporary pediatrics, 2026. 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
methodsA retrospective analysis included 4 824 twin pairs and their mothers with complete records, delivered at 21 tertiary grade-A hospitals nationwide from January 2018 to December 2020. Participants were grouped by prepregnancy BMI: underweight (<18.5 kg/m²;
resultsThe gestational age in the overweight group was lower than in the normal and underweight groups, with a higher rate of very preterm birth (
conclusionsMaternal prepregnancy BMI is closely associated with maternal and infant outcomes in twin pregnancies, providing evidence-based support for individualized weight management.
