Does gestational age influence the predictive accuracy of the cerebroplacental ratio for intrapartum fetal compromise?

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
Background: The accuracy of the cerebroplacental ratio (CPR) in predicting cesarean section for intrapartum fetal compromise (CS-IFC) prior to the onset of labor remains controversial. Objectives: To determine whether advancing gestational age (GA) in the final weeks of pregnancy enhances the predictive performance of CPR and other sonographic parameters for CS-IFC before labor. Study design: This multicentre retrospective study analysed 590 singleton pregnancies across four tertiary centres in Spain, Italy, and the UK. All participants underwent Doppler ultrasound assessment between 35+0 and 41+0 weeks of gestation and delivered within 24 hours of examination. CS-IFC was defined by abnormal intrapartum fetal heart rate patterns or fetal scalp pH <7.20 necessitating emergency caesarean delivery. The predictive performance of CPR, middle cerebral artery (MCA) pulsatility index (PI), and umbilical artery (UA) PI-expressed as multiples of the median (MoM)-was evaluated using ROC curve analysis and logistic regression, alone and in combination with estimated fetal weight centile (EFWc), fetal sex, and type of labour onset (TLO), stratified by gestational age. Results: The highest overall predictive performance between 35 and 40 weeks of gestation was observed with the use of CPR MoM and MCA PI MoM (AUC 0.71, 95% confidence interval [95% CI], 0.64-0.79, Conclusion: The predictive ability of cerebral Doppler for CS-IFC, in both high- and low-risk pregnancies, increases with advancing gestational age during the last weeks of gestation.
