Prognostic factors of sepsis following laparoscopic hiatal hernia repair

Figure 1 Receiver operating characteristic curves for independent predictors of postoperative sepsis. Receiver operating characteristic curves for the combined multivariable model (AUC = 0.812, 95% confidence interval: 0.742–0.882) and each individual independent predictor: ASA class ≥ III (AUC = 0.726), operative time > 180 minutes (AUC = 0.698), and preoperative hypoalbuminemia (AUC = 0.672). The diagonal dashed line represents the reference classifier (AUC = 0.500). The combined model demonstrated a sensitivity of 76.2%, specificity of 74.4%, positive predictive value of 47.1%, and negative predictive value of 91.4%. ASA: American Society of Anesthesiologists; AUC: Area under the curve.
