  1. Legend: N = 100 in the total cohort. The subjects were included in the Normal weight category if the body mass index (BMI) was less than 85% for age and gender, or in the Overweight/Obese category if the BMI were greater than or equal to the 85% for age and gender. The data are expressed as the means ± standard deviation (SD) or median (25-75% interquartile range)
