Hi All!

Even I am getting around CV = 156% (pooled variance estimate) considering N=140 (N=70/group).
Only when N=70 is considered, I am getting CV~92%.

Dear Sereng! From the details of Cmax (Ref): 478 +/- 434 (mean +/- SD) and Cmax (Test): 489 +/- 909 (mean +/- SD), it can be seen that reference Cmax is less variable than test one which is opposite to what is stated in original post. Or is it typo?

Regards,
Divyen
