Data presented as number (%), mean (standard deviation), or median with range. BMI = body mass index, SDS = standard deviation score, SBP = systolic blood pressure, DBP = diastolic blood pressure, MetS = metabolic syndrome, T2DM = type II diabetes mellitus. values for unpaired t-test (normally distributed data), Mann–Whitney U test (nonparametric data), and χ2 tests (categorical data). P values in bold are significant at <0.05.
