CRP, PCT, and JMJD3 were retained as independent predictors of post-NEC intestinal stenosis, leading to the final logistic regression equation: Logit(P) ═ –5.321 + 0.806 × CRP + 0.953 × PCT + 1.136 × JMJD3, where P represents the predicted probability. The gene discussed is CALCA; the disease is necrotizing enterocolitis.
