Value
a 0.70 0.69–0.71 0.548–0.541
b 0.98 0.97–0.99 0.542–0.546
c 0.14 0.12–0.16 0.552–0.537
E/I 0.91 0.54–1.40 0.651–0.447

E/I, ratio of extracellular water (ECW) to intracellular water (ICW) (ECW/ICW); a, fraction of body cell mass (BCM) as water (ICW/BCM); b, fraction of extracellular fluid as water (ECW/ECF); c, ratio of extracellular solids to total body water (ECS/TBW); FFM, fat-free mass. The influence of each determinant on BCM/FFM value can be estimated if a determinant takes its extreme values and the other 3 determinants take their mean values.
