Our objective is to develop ERMF prediction models using real-world data, aiming to identify pertinent contributing factors and support obstetricians in making personalized clinical decisions.  \nMethods: Women who used patient-controlled epidural analgesia between October 2021 and March 2023 at a tertiary hospital in Jiangsu Province were retrospectively documented. The primary outcome was the occurrence of maternal fever associated with epidural use. We developed six machine learning (ML) models and assessed the area under curve (AUC) for characteristics of subjects’ performance, calibration curves, and decision curve analyses.  \nResults: A total of 1,492 women were enrolled, with 24 .3% experiencing ERMF (362 cases) . The AUC ratios between the logistic regression (LR) model and the stochastic gradient descent (SGD) models showed statistical signiﬁcance (p \u003C 0.05), while the differences between the other models were not statistically signiﬁcant. In comparison to the SVM model, the LR model exhibited better calibration (Brier score: 0.193; calibration slope: 0.715; calibration intercept: 0. 062) . Consequently, the LR model was selected as the prediction model. Furthermore, the LR-based nomogram identiﬁed eight signiﬁcant predictors of ERMF, including neutrophil percentage, ﬁrst stage of labor, amniotic ﬂuid contamination during membrane rupture, artiﬁcial rupture of membranes, chorioamnionitis, post-analgesic antimicrobials, pre-analgesic oxytocin, postanalgesic oxytocin, and dinoprostone suppositories.  \nConclusion: Optimally applying logistic regression models can enable rapid and straightforward identiﬁcation of ERMF risk and the implementation of rational therapeutic measures, in contrast to machine learning models.  \nKEYWORDS  \nepidural-related maternal fever, machine learning, predictive model, Nomograms, risk assessment  \nFrontiers in Pharmacology 01 [frontiersin.org](frontiersin.org)  \n1 Introduction  \nEpidural analgesia (EA) has gained widespread acceptance, chosen by a signiﬁcant proportion of women in l","cbCaiecMl3hXg5vu","https://ap.wps.com/l/cbCaiecMl3hXg5vu","pdf",1315165,1,10,"English","en",105,"# Introduction\n# Methods\n# Results\n# Conclusion","[{\"question\":\"What is the main goal of this retrospective study?\",\"answer\":\"To develop prediction models for epidural-related maternal fever (ERMF) using real-world data and to support personalized obstetric decisions.\"},{\"question\":\"How is the ERMF outcome defined and analyzed?\",\"answer\":\"The primary outcome is the occurrence of maternal fever associated with epidural use among women who received PCEA between October 2021 and March 2023.
