a
Median values are reported for baseline descriptive data, as most were not normally distributed.
b
Data for 5 subjects are missing (n = 117) because of processing errors of erythrocytes at the time of collection.
c
Assessed by anthropometric measurements.
d
Assessed by DXA.
e
AndGynFM ratio, andriodal (waist + hip)/gynoidal (thigh) fat mass ratio.
f
Homeostasis model assessment of insulin resistance (HOMA) calculated as follows: Fasting insulin (mU/mL) × fasting glucose (mg/dL)/405.23
