handling of missing data [NCA / SHAM]
I have one question about the handling of the missing data, and need your advice.
My question is:
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.Is there any guideline or reference document we could follow?
My question is:

- Considering from PK personnel’s aspect, as it was not specified in protocol, how would you handling this missed time point at statistical analysis?
- Will this data be included in statistical analysis? If yes, what is the handling procedure?
- If the data is excluded, what kind of method would you use in calculate your AUC?
- Would you adapt interpolation method?
- If yes, would you adapt logarithmic interpolation or linear interpolation?
