The bioimpedance parameters R and S showed marked variability, particularly in the case of S (R mean = 15.9, standard deviation [SD] 11.0; S mean = 82.1, SD 108.9) and there was a highly significant correlation between R and S (R = 0.918, P < 0.001), hence the ratio of R/S was used for subsequent analysis.
