ROC curves of different parameters for MetS predicting. (A) ROC analysis of the THR for MetS predicting according to the Chinese criteria. The AUC of THR was 0.800 (95% CI 0.749–0.852). (B) ROC analysis of the THR for MetS predicting according to the IDF criteria. The AUC of the THR was 0.727 (95% CI 0.669–0.786). AUC area under the ROC curve, FPG fast plasma glucose, HDL-C high-density lipoprotein cholesterol, IDF international diabetes federation, MetS metabolic syndrome, ROC Receiver operating characteristic, TC total cholesterol, TG triglyceride, THR total cholesterol and high density lipoprotein cholesterol ratio.
