Hi Anu,

❝ WinNonlin version 5.3


I strongly suggest to upgrade to Phoenix. WinNonlin 5.3 is not supported any more and buggy (to name a few: λz based on max. R²adj may include Cmax, nonparametric comparison of tmax always in lexical order of treatments, CI obtained from the BE wizard is wrong, whereas from LME is correct – requiring a workaround, …)
Inspectors might ask why you still use an outdated software – although the upgrade was free of charge for 3+ years.

❝ Though treated the WinNonlin sheet as excel sheet and even without detaching it worked. Is it right?


Maybe. Since I installed my latest PHX-license WNL5.3 refuses to start, so I can’t check.

Point estimate:

❝ T/R (Do we consider it as geometric mean ratio or Geometric least square mean ratio?)


I would prefer the latter (aka adjusted mean). Only in a balanced study geometric mean = adjusted mean.
