ROC curve for prediction of central obesity (WC = 90 cm in men and 80 cm in women). (A) for men: cut-off value = 24.7 kg/m2 for men {sensitivity: 92%; specificity: 84%, AUC (95% CI) = 0.95 (0.92-0.97)}. (B) for women: cut-off value = 24.9 kg/m2 for women {sensitivity: 82%; specificity: 91%, AUC (95% CI) = 0.93 (0.91-0.94)}. AUC (95% CI) = area under ROC curves with 95% confidence interval; BMI-F = Body mass index in men, BMI-M = Body mass index in men.
