ECW/TBW according to liver fibrosis stage for all cases (n = 525). The median (range) ECW/TBW in each liver fibrosis stage were: 0.381 (0.366–0.408) in F0-1 (n = 106), 0.380 (0.367–0.399) in F2 (n = 53), 0.384 (0.365–0.402) in F3 (n = 64), 0.389 (0.363–0.428) in Child-Pugh A (n = 226) and 0.395 (0.375–0.433) in Child-Pugh B or C (n = 76) (p values; 0.8808 in F0-1 and F2, 0.0548 in F2 and F3, 0.0002 in F3 and Child-Pugh A, <0.0001 in Child-Pugh A and Child-Pugh B or C, 0.0240 in F0-1 and F3, <0.0001 in F2 and Child-Pugh A, <0.0001 in F3 and Child-Pugh B or C, <0.0001 in F0-1 and Child-Pugh A, <0.0001 in F2 and Child-Pugh B or C and <0.0001 in F0-1 and Child-Pugh B or C, overall significance p < 0.0001). ECW: extracellular water; TBW: total body water.
