Decision-to-delivery interval and neonatal outcomes in intrapartum umbilical cord prolapse.
Article in BMC pregnancy and childbirth, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled it.
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
backgroundRapid delivery is important in cases of umbilical cord prolapse to prevent hypoxic injury to the fetus/neonate. However, the optimal decision-to-delivery interval remains controversial.
objectiveThe aim of the study was to investigate the association between the decision-to-delivery interval in women with umbilical cord prolapse, stratified by fetal heart rate pattern at diagnosis, and neonatal outcome. STUDY
designThe database of a tertiary medical center was retrospectively searched for all cases of intrapartum cord prolapse between 2008 and 2021. The cohort was divided into three groups according to findings on the fetal heart tracing at diagnosis: 1) bradycardia; 2) decelerations without bradycardia; and 3) reassuring heart rate. The primary outcome measure was fetal acidosis. The correlation between cord blood indices and decision-to-delivery interval was analyzed using Spearman's rank correlation coefficient.
resultsOf the total 103,917 deliveries performed during the study period, 130 (0.13%) were complicated by intrapartum umbilical cord prolapse. Division by fetal heart tracing yielded 22 women (16.92%) in group 1, 41 (31.53%) in group 2, and 67 (51.53%) in group 3. The median decision-to-delivery interval was 11.0 min (IQR 9.0-15.0); the interval was more than 20 min in 4 cases. The median cord arterial blood pH was 7.28 (IQR 7.24-7.32); pH was less than 7.2 in 4 neonates. There was no correlation of cord arterial pH with decision-to-delivery interval (Spearman's Ρ = - 0.113; Ρ = 0.368) or with fetal heart rate pattern (Spearman's Ρ = .425; Ρ = .079, Ρ = - .205; Ρ = .336, Ρ = - .324; Ρ = .122 for groups 1-3, respectively).
conclusionIntrapartum umbilical cord prolapse is a relatively rare obstetric emergency with an overall favorable neonatal outcome if managed in a timely manner, regardless of the immediately preceding fetal heart rate. In a clinical setting which includes a high obstetric volume and a rapid, protocol-based, response, there is apparently no significant correlation between decision-to-delivery interval and cord arterial cord pH.
