TABLE 3.

Multilevel mixed-effects linear regression using natural log transformation based on all MPA measurements except those in the steroid-free arm performed on concomitant steroid therapy (n = 462).

CS effect on MPA AUC - no concomitant steroid in the steroid-free arm
lnAUC	β ln (mg*h/L)	[95% conf. Interval]	p-value
Steroid-free arm	−0.077	−0.15 to −0.0045	0.04
MMF (mg)	0.00028	0.00021 to 0.00035	<0.001
TAC trough level (ng/ml)	−0.0043	−0.012 to 0.0036	0.28
Weight (kg)	−0.0049	−0.0071 to −0.0027	<0.001
Time after transplantation (months)	0.0072	0.0017 to 0.013	0.01

lnAUC = natural log transformation of AUC.
