1 · What the graph read from 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.

2 · The registry

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: While maternal intrapartum fever is linked to adverse neonatal outcomes, predictive tools for delivery mode and neonatal intensive care unit (NICU) admission in this population remain scarce. Objective: To develop and validate a dynamic nomogram predicting cesarean delivery and NICU admissions in women with intrapartum fever, facilitating individualized intrapartum decision-making. Methods: This retrospective cohort study analyzed 24,784 deliveries (2019-2021) at a tertiary center. After exclusions, 1,047 women with intrapartum fever were included in the study cohort. The dataset was randomly partitioned into training (n=837) and testing (n=210) sets. Backward stepwise multivariable logistic regression models were developed to predict cesarean delivery and neonatal intensive care unit admission. The discriminative capacity of the model was evaluated using receiver operating characteristic (ROC) curve analysis. Calibration performance was assessed via 1000 nonparametric bootstrap resamples to generate calibration curves, with systematic quantification of agreement between predicted probabilities and observed outcomes through the Brier score and Hosmer-Lemeshow goodness-of-fit test. Results: Predictors of cesarean delivery included advanced maternal age, hypertensive disorders, Intrapartum Antibiotic Prophylaxis (IAP), Meconium-Stained Amniotic Fluid (MSAF), Macrosomia, Postpartum Hemorrhage (PPH), Oligohydramnios, assisted reproductive technology (ART), Hypertensive Disorders of Pregnancy (HDP), Maternal tachycardia, Placental histopathology, intrapartum temperature and Method of inducing labor. Low Birth Weight (LBW), adverse obstetric history (AOH), Fetal tachycardia, Fetal bradycardia, Scarred uterus, Maternal tachycardia and MSAF predicted neonatal intensive care unit admission. The cesarean delivery model achieved AUC of 0.8 (training) and 0.783 (testing); the neonatal intensive care unit admission model showed AUC of 0.681 (training) and 0.748 (testing). Conclusion: This nomogram provides a clinically useful tool to predict delivery mode and neonatal intensive care unit admission in women with intrapartum fever, aiding risk stratification and improving perinatal outcomes.
