Participant characteristics by obesity status. Continuous variables are presented as median with their respective interquartile range (IQR). Percentages listed are percent of the total number of normal/overweight or obese participants. BMI: Body mass index. Bolded p-values are significant p-values (p-values<0.05). Significance of categorical data was determined by chi-squared test and significance of continuous variables was determined by Kruskal–Wallis test.
