n	12
Age (years)	34.7 ± 1.3
BMI (kg/m2)	22.10 ± 0.66
Abdominal circumference (cm)	79.4 ± 1.9
HbA1c (%)	4.88 ± 0.07
FPG (mg/dL)	95.8 ± 3.62
HOMA‐β	52.9 ± 9.4
HOMA‐IR	0.78 ± 0.15

HOMA‐β was calculated as IRI₀ × (FPG − 63), where IRI₀ is the fasting serum insulin concentration.

HOMA‐IR was calculated as FPG × IRI₀/405.

BMI, body mass index; FPG, fasting plasma glucose.
