  1. Method: Categorical variables were expressed as numbers and percentages, while continuous variables were presented as means (SD) or medians (IQR). Student’s t-test or Mann-Whitney U-test was used to compare normally distributed numeric variables or non-normally distributed continuous variables, respectively. P for excess weight vs. normal weight. p for obesity vs. normal weight
