ROC curve for prediction of central obesity (WC = 102 cm in men and 88 cm in women). (A) for men: cut-off value = 27.1 kg/m² {sensitivity: 96%; specificity: 81%, AUC (95% CI) = 0.94 (0.91-0.96)} (B) for women: cut-off value = 26.8 kg/m² {sensitivity: 82%; specificity: 89%, AUC (95% CI) = 0.93 (0.91-0.95)} 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.
