Association between Pre-pregnancy BMI and Pregnancy Outcomes in Women with Gestational Diabetes: A Retrospective Cohort Study.
Article in Pakistan journal of medical sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Background & Objective: The specific influence of the pre-pregnancy body mass index (PPBMI) on women with gestational diabetes mellitus (GDM) is unclear. Our objective was to investigate how PPBMI categories affect pregnancy and neonatal outcomes in women with GDM. Methods: A retrospective cohort study was conducted using data from patients attending the Fujian Maternity and Child Health Hospital (Fuzhou, China) from 2021 to 2023. The participant records were stratified into four groups according to their BMI values: underweight, normal-weight, overweight, and obese. The pregnancy and neonatal outcomes for these BMI categories were analyzed using multivariable logistic regression. Results: The study included data from 2,909 pregnant women diagnosed with GDM. Underweight women with GDM showed significantly lower risks of pregnancy-induced hypertension (PIH) (adjusted OR, 0.26) and cesarean sections (adjusted OR, 0.55) but higher risks of low body weight (LBW) infants (adjusted OR, 3.40). Overweight and obese women experienced higher risks of PIH (adjusted OR, 2.96), cesarean sections (adjusted OR, 1.62), and macrosomia (adjusted OR, 1.43). Conclusion: PPBMIs significantly impact pregnancy outcomes in women with GDM. Both underweight and overweight/obese categories are associated with adverse outcomes, highlighting the need for pre-pregnancy counseling and interventions to achieve and maintain a healthy BMI.
