Hi Nirali,

» If the 95% upper bound for Cmax parameter is 0.002, should we conclude this study as a bioequivalent for Cmax?

No, since the upper bound has to be less or equal to zero. No rounding here …

» There is no specific criteria given for 95% upper bound in the OGD of Warfarin Sodium.

≤0 is the general rule for the FDA’s RSABE.
