Sensitivity analysis of the cut-off value.

Sn, sensitivity; Sp, specificity; CI, confidence interval; ROC, receiver operating characteristic.*84 mg/g of creatinine (8.4 mg/mmol) for the TPCR was the optimal cut-off value to predict microalbuminuria based on the receiver operating characteristic curve analysis.Sn（灵敏度，sensitivity）、Sp（特异度，specificity）、CI（置信区间，confidence interval）、ROC（受试者工作特征曲线，receiver operating characteristic）。* 基于受试者工作特征曲线分析，TPCR（总蛋白肌酐比）的84 mg/g肌酐（8.4 mg/mmol）为预测微量白蛋白尿的最佳截断值。
