Hi Helmut,
Actually that particular CRO (maybe there are others) kept the subject's Cmax, Tmax and AUCt but assigned AUCinf, kel and t1/2 as undefined or "N.C."
One more question, what if the last two points of the elimination phase is going in the positive direction and the points before them (lets say 3 points, yes after Cmax) are declining?
❝ ❝ Should Kel be labelled as "Undefined"? Some CROs would say "Undefined" …

❝ That would mean excluding the subject’s AUCs (AUCt unreliable, AUC∞ undefined). At least you could keep the subject’s Cmax in the data set (which is more variable).
