Registerhandling of missing data [NCA / SHAM]
Dear Gracehung,
I understand you question differently from Helmut. My understanding is that the sample was collected, but the phlebotomist failed to record the actual blood sampling time. In such a case I would just file a protocol deviation and re-train the staff, full stop. Even if there were a sampling time deviation, the influence on the AUC 90 % CI is so limited that it would only change the outcome of the trial in a very borderline situation.
❝ As in BE study, One sample’s actual sampling time was miss recorded. However as according to protocol, this sample was analyzed by our analytical laboratory.
