Predicting neonatal respiratory distress syndrome in late preterm infants.

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
backgroundLate preterm births (34 + 0-36 + 6 gestational weeks) comprise 75% of preterm deliveries and are at increased risk for respiratory distress syndrome (RDS), a leading cause of neonatal morbidity. We aimed to develop a predictive model for RDS in late preterm neonates based on maternal and prenatal clinical variables available before the onset of labor.
methodsA retrospective cohort study was conducted in a tertiary medical center between May 2016 and June 2023. The institutional healthcare database was searched for all women who gave birth to a singleton neonate at 34 + 0-36 + 6 gestational weeks. Three models were applied to predict the likelihood of development of neonatal RDS: multivariable logistic regression, conditional inference trees (CIT), and extreme gradient boosting (XGBoost).
resultsOut of 37,205 deliveries during the study period, 2,444 singleton neonates were included, of whom 137 (5.6%) were diagnosed with RDS. Multivariable logistic regression analysis identified five significant predictors of RDS: gestational age (aOR 0.35, 95%CI: 0.32-0.38), male sex (aOR 1.68, 95%CI: 1.47-1.92), cesarean delivery (CD) (aOR 1.28, 95%CI: 1.20-1.37), nulliparity (aOR 0.47, 95%CI: 0.40-0.54) and antenatal corticosteroids (ACS) (aOR 0.54, 95%CI: 0.45-0.64 for administration before 34 weeks; aOR 0.60, 95%CI: 0.49-0.72 for administration after 34 weeks). These findings represent predictive associations rather than causal treatment effects. Among the predictive models, the logistic regression demonstrated the highest discriminatory performance with an area under the curve (AUC) of 0.75 (95% CI: 0.70-0.79), followed by XGBoost algorithm with an AUC of 0.70 (95% CI: 0.66-0.75), and CIT with an AUC of 0.68 (95% CI: 0.64-0.73).
conclusionsModels based on prenatal maternal and fetal characteristics demonstrated modest discrimination but strong negative predictive value for identifying RDS in late preterm infants. Such tools may assist with antenatal counseling and support decisions regarding the appropriate level-of-care setting for delivery. Further studies are needed to validate these findings and to explore whether incorporating additional clinical variables can enhance predictive performance.
