Log HOMA model p-Value MetS cluster z-score model p-Value
Sex

BMI and AN
 BMI < 85th percentile 1.3 (1.1– 1.6) < 0.001 a − 0.27 (− 0.42 to − 0.11) < 0.001 b
 BMI 85th– 94.9th percentile with −AN 2.2 (1.2 – 4.1) 0.24 (− 0.33 to 0.81)

a

The BMI < 85th percentile group is significantly different from the BMI ≥ 95th percentile + AN group.

b

The BMI < 85th percentile group is significantly different from the BMI 85th – 94.9th percentile with + AN group and the BMI ≥ 95th percentile + AN group.
