ROC curve graphic comparing five models: preoperative albumin, POD2 nadir albumin, delta albumin, rocuronium, and a combined model. Combined model shows the highest performance with an AUC of 0.794, while delta albumin has the lowest with an AUC of 0.536. Sensitivity is plotted against 1 minus specificity for each model. — Receiver operating characteristic (ROC) curves for individual predictors (preoperative albumin, POD2 nadir albumin and rocuronium) and for DAlb, with the combined multifactorial model shown for comparison. DAlb discriminated near chance (AUC 0.536), whereas the combined model achieved the highest AUC (0.794). AUC = area under the curve.
