Relationship between ultrasound and BIA in muscle mass evaluation. The correlation between ultrasound and two BIAs. a Muscle mass. b Muscle mass change. a Muscle mass was compared at one point in each measurement day. BIA was correlated with ultrasound in some measurement days (Bioscan, days 1, 5, 7, and 10; Physion, days 1 and 5). b Muscle mass change was compared from day 1 to each measurement day. The percentage change of muscle mass in BIA did not correlate with the findings using ultrasound. The correlations were shown under every graph. Pearson correlation coefficient was used to investigate the relationships. BIA bioelectrical impedance analysis
