Dear HS and all,
  1. What are the reasons that can be given for exclusion of subject from statistical analysis, having more than two missing time points.
  2. On what basis we can decide the uncritical region.
  3. By interpolation (linear in the rising part, log/linear after tmax) do you mean that we have to show un-transformed or raw data to be linear in rising part and after tmax ln-transformed data to be linear. Kindly clarify and give a breif idea about what do you mean by interpolation.
Regards,

Atish
