The nomogram identifies eight key predictors for ERMF prediction: neutrophil percentage, first stage of labor, amniotic fluid contamination during membrane rupture, artificial rupture of membranes, chorioamnionitis, post-analgesic antimicrobials, pre-analgesic oxytocin, post-analgesic oxytocin, and dinoprostone suppositories (refer to Figure 4). This evidence concerns the gene OXT and chorioamnionitis.
