^aChange in OBJF in comparison to preceding model with an advantage.

^bImprovement on preceding model with significant effect (based on ΔOBJF and 95% confidence interval).

^cThis model which incorporates the effects of age on CL, body surface area on V, weight and total bilirubin on F was selected as BASE 3.
