WebInter-dose AUC (ie, most generally AUC 0–12 h) is more informative than C 0 because it correlates better with rejection in patients with kidney transplants [16–18]. However, AUC 0–12 h estimation based on a complete pharmacokinetic profile requires multiple blood samples over a 12-h period, which is uncomfortable for the patient and costly.

Two syntaxes are possible: one object of class “roc”, or either two vectors (response, predictor) or a formula (response~predictor) as in the roc function. By default, the total AUC is computed, but a portion of the ROC curve can be specified with partial.auc.
