Table 3 Intra- and inter- evaluator intraclass coefficient of correlation for BIS R0

Bioimpedance BIS R0 reliability for limb percentage difference
	Baseline	D2	D8
Intra-evaluator ICC (1 ^st ; 2 ^nd evaluator)	0.90; 0.93	0.99; 0.96	0.98; 0.98
Inter-evaluator ICC (1 ^st ; 2 ^nd measurement)	0.89; 0.97	0.98; 0.98	0.97; 0.99

All ICC are significant at P < 0.01.
