Abbreviations: BMI: body mass index, IQR: interquartile range, SD: standard deviation. Between-group differences were determined using independent sample t-test for parametric variables (*), Mann Whitney U test for non-parametric parameters (¶), and Chi-square (†) or Fisher exact (‡) tests for categorical variables. Bold denotes statistical significance (P-value < 0.05)
