| WC (cm) | 0.638 (0.562-0.713) | 97.25 (53.9; 70.1) | <0.001 |
| HOMA-IR | 0.677 (0.597-0.757) | 4.527 (56.5; 74.6) | <0.001 |
| FI (mlU/L) | 0.639 (0.561-0.718) | 19.2 (54.9; 69) | <0.001 |
| BIA TBF% | 0.657 (0.558-0.756) | 46.15 (62.8; 62.8) | 0.002 |

AUC: area under curve, CI: confidence interval, BMI SDS: body mass index standard deviation score, WC: waist circumference, HOMA-IR: homeostatic model assessment for insulin resistance, FI: fasting insulin, BIA TBF%: bioimpedance analysis derived total body fat percentage, BIA VF: bioimpedance-derived visceral fat level. Statistical significance was set at p<0.05.
