Models were developed from the validation group.

Age was counted in full.

The preliminary model (total): (‘54.601’ for male and ‘66.622’ for female)

Female 40-59 yr: 66.379-945.604×1/BMI + 3599.326×1/BMI2

Female ≥60 yr: 67.093-945.604×1/BMI + 3599.326×1/BMI2

R2 is explanatory power.

BMI, body mass index; SEE, standard error of estimate; TE, total error.
