(a) Total group: area under curve (AUC) were 0.827 (95% confidence interval (CI) 0.791 to 0.864). (b) The subgroup of patients with newly diagnosed type 2 diabetes: AUC were 0.832 (95% CI 0.754 to 0.911), cut-off point  = 10.1%, sensitivity  = 88.76%, specificity  = 65.00%. (c) The subgroup of patients with previously diagnosed of type 2 diabetes: AUC were 0.811 (95% CI 0.767 to 0.856), cut-off point  = 8.6%, sensitivity  = 86.59%, specificity  = 62.00%.
