Receiver operating characteristic (ROC) curves for obesity indices. a. Metabolically healthy obesity (MHO) criteria ≤2, b. MHO criteria ≤1, c. MHO criteria = 0. The blue lines indicate body mass index (BMI), the green lines indicate appendicular skeletal muscle (ASM), the red lines indicate waist circumference (WC), the purple lines indicate waist to height ratio (WHtR), the brown lines indicate body fat % (FAT), and the red lines are reference lines. The obesity indices showed different sensitivities and specificities. WC and WHtR were the most sensitive indicators of MHO, as defined by the fulfillment of MS risk factors = 0 (AUC = 0.846 for WC and 0.824 for WHtR in men, and 0.970 for WC and 0.944 for WHtR in women).
