Data are presented as the median (IQR) or frequency (percentage). P-values are calculated using the Chi-square test for proportions and the Kruskal–Wallis test for medians among the three BMI groups. Letter a,b,c indicated significant difference between groups.
a
P: Comparison between Normal weight and Overweight patients.
b
P: Comparison between Overweight and Obese patients.
c
P: Comparison between Normal weight and Obese patients.
