Reliability test for InBody S10; intra-class correlation coefficient in test-retest.

	Test 1	Test 2	Test 3	ICC
Factors	Mean ± SD	Mean ± SD	Mean ± SD	(95% CI)	P value
Affected arm ECW/TBW ratio	0.390 ± 0.009	0.391 ± 0.009	0.391 ± 0.009	0.998	<.001
Unaffected arm ECW/TBW ratio	0.381 ± 0.006	0.381 ± 0.006	0.381 ± 0.005	0.997	<.001
Inter-limb 1 kHz impedance ratio	1.215 ± 0.203	1.218 ± 0.206	1.222 ± 0.208	1.000	<.001

CI = confidence interval, ECW = extracellular water, ICC = intra-class correlation coefficient, SD = standard deviation, TBW = total body water.
