p-value indicates significant difference between groups (p<0.05). Continuous variables were compared by Wilcoxon rank-sum, and categorical variables were compared by Chi-squared test. Continuous variables are reported as median and interquartile range (IQR) in parentheses. Categorical variables are presented as the proportion (%) of children in each group who had the characteristic.
