    Result interpretation

    Deze formule berekent de geschatte vetvrije massa (lean body mass) volgens James (1976).

    Model prestaties:
    Gegevens over de originele studie verricht door James W.1 in 1976 bleken niet beschikbaar. In een studie verricht door Absalom et al (2009)2, bleek de James formule goed te presteren in patiënten met een normale tot mild verhoogde BMI. Bij morbide obese patiënten werden paradoxale resultaten gezien.
