Postpartum hemorrhage incidence and risk factors: Evidence from a multicenter study in Zhejiang Province, China.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectivePostpartum hemorrhage (PPH) is a leading cause of maternal mortality worldwide, and its risk factors vary regionally. This study assessed the incidence and determinants of PPH in Zhejiang Province, China.
methodsWe conducted a cross-sectional study using data from the Maternity Near Miss Surveillance System in Zhejiang Province, collected from January to December 2020. The cohort included 56,014 pregnant women at a gestational age of 28 weeks or more. PPH was defined as blood loss of ≥500 mL for vaginal deliveries and ≥1,000 mL for cesarean sections within 24 h of delivery. Logistic regression analyzed the risk factors for PPH.
resultsOf the pregnant women, 2,016 (3.60%) experienced PPH. The mortality rate associated with PPH was 1.74 per 100,000 live births. Significant independent risk factors included multiple births (OR 3.10; 95% CI 2.42-3.98; P < 0.01), vaginal delivery (OR 3.00; 95% CI 2.62-3.42; P < 0.01), macrosomia (OR 2.30; 95% CI 1.97-2.68; P < 0.01), hypertensive disorders of pregnancy (OR 1.79; 95% CI 1.50-2.13; P < 0.01), and a lower educational level (OR 1.20; 95% CI 1.07-1.36; P < 0.01).
conclusionThe incidence and mortality rates of PPH in Zhejiang Province are low. Identified risk factors such as multiple births, vaginal delivery, macrosomia, hypertensive disorders, and lower education level can guide interventions to mitigate PPH risk.
