“…Limited-sampling strategies based on 2, 3, or 4 time points yield good correlation with 12-hour AUC [3]. Correlations are better with 4-time-points sampling [5,7,8]. We used 4 time point measurements of MMF (C0, C1, C2, and C4) which has a Pearson correlation with the 12-hour AUC of r 2 ¼ 0.945 (95% CI, 0.905e0.969) [7].…”
