AUC for WHtR [0.032 (0.026 (0.002–0.050), P=0.032, (0.036 (0.064–0.007), P=0.013, 0.022 (0.008–0.036), P=0.002] was significantly higher than BAI and WHpR and WC respectively; no other significant differences were observed in men.
No significant differences were observed in women.
BMI - Body mass index; WC - waist circumference; WHpR - waist-to-hip ratio; WHtR - waist-to-height ratio;
LR+ - positive likelihood ratio; LR- - negative likelihood ratio; AUC - area under the curve; CI - confidence interval
