The Risk Factors for Placental Abruption in Preeclamptic Pregnancies: A Retrospective Case-Control Study.
Article in The journal of obstetrics and gynaecology research, 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
aimPreeclampsia poses a high-risk factor for placental abruption. The precise understanding of the accompanying symptoms and disease phenotype of preeclampsia, in order to promptly identify the occurrence of placental abruption in preeclamptic women, remains unclear.
methodsThe obstetric data of preeclamptic women were retrospectively analyzed between January 2016 and June 2023 in our hospital. Based on the presence or absence of placental abruption, they were categorized into two groups: placental abruption group and non-placental abruption group. Logistic regression analysis was employed to identify risk factors for placental abruption in preeclamptic women.
resultsA total of 709 preeclamptic women were enrolled, of whom 39 cases experienced placental abruption. Compared to the non-placental abruption group, the placental abruption group exhibited a younger age, lower BMI at delivery, and higher incidence of HELLP syndrome (p < 0.05). The risk factors for placental abruption in preeclamptic women included systolic blood pressure/10 (aOR 1.293, 95% CI 1.031-1.613), blurred vision (aOR 3.847, 95% CI 1.175-12.600), positive urine protein (aOR 3.081, 95% CI 1.157-8.208), platelet count/10 (aOR 0.923, 95% CI 0.860-0.991), and maternal age (aOR 0.899, 95% CI 0.836-0.966). The placental abruption group had shorter gestational age at delivery and higher rates of cesarean section delivery, fetal growth restriction, and neonatal asphyxia (p < 0.05).
conclusionsThe occurrence of placental abruption in preeclampsia significantly impacts neonatal well-being. Close monitoring of blood pressure, particularly systolic blood pressure, urine protein, platelet counts, and visual acuity is crucial for preeclamptic women to early identify the occurrence of placental abruption.
