A retrospective study on the impact of the timing of diabetes diagnosis on maternal and fetal outcomes.
Article in Archives of gynecology and obstetrics, 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
purposeThis study aimed to evaluate the impact of the timing of diabetes diagnosis on maternal and fetal outcomes.
methodsThe data were collected from pregnant women diagnosed with pregestational diabetes mellitus (PGDM) who were hospitalized at Dongguan People's Hospital between June 2016 and December 2023. Based on the timing of diagnosis, women were categorized into two groups: those diagnosed before pregnancy and those diagnosed during pregnancy. General clinical characteristics, glycemic control, pregnancy complications, and maternal and fetal outcomes were compared between the two groups to assess the influence of diagnosis timing on pregnancy outcomes.
resultsBetween 2016 and 2023, a total of 415 pregnant women with PGDM were included in this study. Among them, 242 (58.31%) were diagnosed before pregnancy, while 173 (41.69%) were diagnosed during pregnancy, resulting in a preconception diabetes awareness rate of 58.31%. Education level was significantly associated with the timing of diabetes diagnosis (P = 0.002). In addition, women diagnosed during pregnancy had significantly higher HbA1c levels before delivery when compared with those diagnosed before pregnancy (6.70% vs. 6.20%, P < 0.001), indicating more severe glycemic dysregulation. Consequently, this group also exhibited a higher rate of diabetes-related hospitalizations during pregnancy (42.77% vs. 22.73%, P < 0.001) and an increased risk of macrosomia (20.23% vs. 10.74%, P = 0.007).
conclusionPregnant women diagnosed with diabetes during pregnancy exhibited more severe perinatal glucose metabolism disorders and a higher rate of macrosomia. Early diagnosis and management of diabetes-especially before conception-helped improve perinatal glycemic control, potentially reducing healthcare burdens and the incidence of macrosomia.
