Burmeister and Bingert reported equations for estimating a patient’s body cell mass (BCM). The authors are from Universitats-Kinderklinik Homburg and Institut fur Angew. Mathematik Saarbrucken.
Patient selection: ages 8 to 90 years
Parameters:
(1) age in years
(2) weight in kilograms
(3) height in cm
Gender
Age in years
LN(body cell mass in kilograms) =
