Figure 7. Relation of volume of distribution (V/Foral) estimates to age. Individual V/Foralestimates (open diamonds; 1) increase with age when no correction is made for size. When these estimates are standardized to a 70-kg person using an allometric 3/4 power model (filled squares; 1/70 kg body weight), there is no influence of age on the prediction of V/Foral.
