Mean Expected Error in Prediction of Total Body Water: A True Accuracy Comparison between Bioimpedance Spectroscopy and Single Frequency Regression Equations

Table 3

BIS volume prediction equations using de Lorenzo’s method [22].

Body fluid	Equation	Variable values
ECW		= 4.3; = 1.05 × 10^−3; = 40.5 for men
ICW		= 39 women; = 273.9 men; = 264.9 women

Note: ICF is obtained after solving the resulting 5th grade equation after substituting = ICW/ECW according to [23].
