Hi Mohamed Yehia,

❝ What to do if Normality shapiro-wilk test on Ln transformed Auc and cmax are non normal?. Can we proceed using parametric analysis test "Anova"?. As according to my knowledge, we can't use any parametric analysis tests on non normal data.


You don't have much choice in practice, generally.
BE data from human trials are always -as far as I know- analysed using parametric testing (linear model for the effects and residuals, derivation of 90% CI via the model residual, typically an ANOVA on top of all that). You are not even supposed to do a SW-test or similar. Any test for distributional departure will not have impact on the choice of method.

Pass or fail!
