Predictive value of risk factors for early major POCD in elderly patients with gastrointestinal tumors by ROC curve analysis. The area under the curve (AUC) of VAS score for POCD was 0.860, with the cut-off value of 2.68, sensitivity of 87.5% and specificity of 74.8%, respectively (95% CI: 0.801–0.920, P < 0.001). ROC: receiver operating characteristic; NLR: neutrophil-lymphocyte ratio; AUC: area under the curve; CI: confidence interval; POCD: postoperative cognitive dysfunction
