Evaluation of the first trimester maternal glycolipid profile on gestational diabetes mellitus: a case-control study in the hospital of rural Shanghai.
Article in BMJ open, 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
objectivesThis study aimed to accurately assess the risk of gestational diabetes mellitus (GDM) and examine the interactive effects of first-trimester glycolipid metabolism and inflammatory factors on GDM development among women in southeastern China.
designA case-control study.
settingA primary and comprehensive hospital in rural Shanghai, China.
participantsParticipants were recruited from the electronic medical record database of Shanghai University of Medicine & Health Sciences Affiliated Zhoupu Hospital in 2019. A total of 678 participants with complete medical records were enrolled. Women were included if they (1) were registered Shanghai residents with no plans to move out of Shanghai within the following 2 years, (2) attended their first prenatal visit before the 20th week of gestation, (3) planned to give birth at Zhoupu Hospital and (4) had complete medical history and laboratory data as well as regular prenatal visits (≥6) before delivery. Women were excluded if they met any of the following criteria: (1) type I or II diabetes mellitus, (2) chronic hypertension, (3) prior drug treatment for dyslipidaemia, (4) cardiovascular diseases or (5) other diseases contraindicating pregnancy. We retrospectively collected data from the electronic health records of 2255 participants at the hospital in 2019. Ultimately, 678 pregnant women, including 133 with GDM and 545 with normal glucose tolerance, were included in the final analysis.
resultsC-reactive protein (CRP), triglycerides (TG), lymphocyte count and glycated haemoglobin (HbA1c) were all associated with an increased risk of GDM (
conclusionsElevated maternal glycolipid metabolism and altered inflammatory marker levels during early pregnancy may increase the risk of GDM in the rural area in Shanghai, China. The interactions among CRP, TG, lymphocyte count, HbA1c and age/BMI may contribute to GDM development. Future external validation studies are needed to confirm these findings in larger cohorts and more diverse populations.
