  1. IQR, interquartile range. The underestimated group was defined as the subjects with >  − 5 kg from their actual body weight. The acceptable group was defined as the subjects within ± 5 kg from their actual body weight. The overestimated group was defined as the subjects > 5 kg from their actual body weight. The p-values were calculated by performing the Kruskal–Wallis test.
