Association of hypertensive disorder of pregnancy with necrotizing enterocolitis in very preterm infants: A retrospective cohort study.
Article in PloS one, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Hypertensive disorders of pregnancy (HDP) may affect fetal development and result in preterm delivery. Necrotizing enterocolitis (NEC) is a severe gastrointestinal emergency in very preterm infants (VPIs, gestational age less than 32 weeks). The relationship between maternal HDP and NEC is controversial. Objective To investigate the association between maternal HDP and NEC in VPIs.This was a multicenter retrospective cohort study based on the data from the Chinese Neonatal Network (CHNN) which were collected between January 1, 2019 and December 31, 2021. Preterm infants born between 24+0 and 31+6 weeks of gestation were divided into HDP and no-HDP groups according to the 2015 Chinese guidelines for HDP. The primary outcome was the incidence of Bell's stage II or higher NEC. Secondary outcomes included mortality and spontaneous intestinal perforation (SIP). Of 27,660 women were included in the study analysis, 5405 (19.5%) were HDP and 22256 (80.5%) were no-HDP. NEC occurred in 5.2% (283/5,404) among HDP mothers and 5.3% (1,191/22,256) among no-HDP mothers. No significant association was observed between HDP and Bell's stage II or higher NEC (aOR 0.87, 95% CI [0.72, 1.05]). However, even after adjustment, maternal HDP appeared to be protective for NEC requiring surgical intervention (aOR 0.60, 95% CI [0.43, 0.83]). There was no significant correlation between maternal HDP and neonatal mortality and SIP. Maternal HDP was not significantly associated with the incidence of Bell's stage II or higher NEC. However, it was associated with the lower rate of NEC requiring surgical intervention.
