Hello everybody!

I did a software validation of WinNonlin with R program and in the ANOVA analysis I got the following results for the sequence effect:

AUC0-t.

-BEAR
Tests of Hypothesis using the Type III MS for SUBJECT(SEQUENCE) as an error term

Sequence Effect: F-value = 8.4; Pr>F=0.00958

-WINNONLIN

Sequence Effect: F-value = 4.593; P_value = 0.07053

As you can see according to bear there is a sequence effect for AUCo-t while in WinNonlin it's not. This same situation happen with AUC0-Inf.

However, the results for NCA, period, drug, seq(subj) effect, Confidence Intervals are exactly the same in both programs. So, why only the sequence effect is different?

Thank you for your answer on understanding this situation.

Risherd.
