Hello Mittyri,

thank you for your comment regarding the denominator used for testing Group*Tretament effect, highly appreciated.

❝ ❝ Which dataset are you talking about? Some random dataset or a specific one?

❝ No preferences in exact dataset, but it would be good to test the dataset with unequal groups length

❝ ❝ And you are talking about testing Group*Treatment interaction with this dataset with both PROC MIXED and PROC GLM and to see if there is any difference?

❝ yes, if possible please

In SAS I performed ANOVA with dataset with unequal group sizes (and with subjects that completed both periods) with both PROC MIXED and PROC GLM to test Group*Treatment effect and the p-values for all PK parameters do not differ between PROC MIXED and PROC GLM. So you were right
