  1. Mean and SD of R and X as well as TBW determined directly by D2O dilution (TBWd) and indirectly with Eqs. (1) (TBW1) and (2) (TBW2) with values obtained using a portable bioelectric impedance device [resistance (R) and reactance (X)] and morphological parameters. Diff1 and Diff2: differences between the TBWd value and the TBW values computed with Eqs. (1) and (2), respectively.
