Dear All,

As per Draft Guidance on Warfarin Sodium bioequivalence criteria for NTID as

Every study should pass the scaled average bioequivalence limits and
Also regular unscaled bioequivalence limits of 80.00-125.00%.
the upper limit of the 90% equal-tails confidence interval for σ_wT/σ_wR is less than or equal to 2.5

My understanding for 1 and 2 criteria as below,

The 95% upper confidence bound for (Y_T – Y_R)² – θs²_wR must be ≤ 0 and the point estimate of the Test/Reference geometric mean ratio must fall within 80.00 – 125.00%. (scaled average bioequivalence limits)
90% confidence interval should lies within 80–125% (unscaled bioequivalence limits)

Is this correct? Please guide me to understand the bioequivalence criteria of NTI drugs.

Thanks in advanced.
