(A) Nomogram of logistic regression model. This nomogram was developed with eight perioperative predictors. Find each predictor's point on the uppermost point scale and add them up. The total point projected to the bottom scale indicates the % probability of POD. (B) Calibration curve of logistic regression model for the training dataset. (C) DCA of logistic regression model for the training dataset. ASA, American Society of Anesthesiologists physical status classification system; WBC, white blood cell. DCA, decision curve analysis
