Association between hypertensive disorders of pregnancy and disease progression in preterm infants with necrotizing enterocolitis: a retrospective cohort study.
Article in European journal of medical research, 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
introductionThe aim of this study was to investigate the association between hypertensive disorders of pregnancy (HDP) and disease progression in preterm infants with necrotizing enterocolitis (NEC), providing a basis for risk-stratified monitoring.
methodsWe conducted a retrospective cohort study of 237 preterm neonates diagnosed with Bell stage II NEC at a tertiary level teaching hospital in China between January 2015 and January 2025. Statistical analyses included univariate analysis, multivariate logistic regression, smooth curve fitting, and threshold effect analysis.
resultsAmong the 237 mothers included, 54 (22.78%) presented HDP. Disease progression (to Bell stage III or death) occurred in 71 NEC patients (29.96% of the cohort). Infants in the HDP group presented a significantly lower progression rate compared to the non-HDP group (16.67% vs. 33.88%; OR, 0.36 [95% CI 0.14-0.92]). Furthermore, systolic blood pressure (SBP) was negatively correlated with NEC progression when the mean SBP was less than 171.20 mmHg, with each 1 mmHg increase associated with a 2% reduction in progression risk (95% CI, 0.96-0.99).
conclusionsMaternal HDP and a SBP < 171.2 mmHg were associated with a decreased risk of NEC progression in preterm infants with Bell stage II NEC. These findings suggest that maternal blood pressure monitoring and hypertensive status may inform clinical decision-making in NEC management.
