1p for trend was evaluated by Jonckheere-Terpstra test. 2 Comparison of median values between the three BMI groups were performed with Steel-Dwass test, and p values were given for each group comparison. 3 Comparison of median values between the two groups were performed with Mann-Whitney U test. SD; standard deviation, IQR; interquartile range.
