Dear Khaoula,

I re-calculated your C_max-data in Kinetica v5.0.10. I didn’t import the “all missing” row of subject #15 and asked for log-transformed analysis. Now I’m even more confused. Below my results:

BIOEQUIVALENCE TESTS FOR

Level R and level T



Reference Confidence Interval: [0.8, 1.25]


Geomean Ratio (Test/Reference) = 1.21205

90% standard confidence interval

(around the ratio:[test form]/[ref form])=[1.0448, 1.4061]


t(0.05 - 13df) = 1.7709



  Cannot conclude equivalence.

Still wrong in many places, but closer to Phoenix/WinNonlin and R.
