Values presented as mean ± standard deviation and frequencies (%).
Bod-pod=air displacement plethysmography.
BVI= Body volume index obtained from the 3D scanner.
BFM=Body fat mass
Observed values were obtained from Bod-pod.
Predicted values were estimated in the validation set using BVI parameters.
α
Derived with the Siri equation using observed Bod-pod volume and total mass.
π
Derived with the Siri equation using predicted Bod-pod volume and total mass.
