Dear John

❝ Original fasting study was n=47, rechallenge was n=8 with 5 questionable subjects + 3 controls; The 5 questionable subjects were suspected as outliers because their Cmax ratios were greater than ± 2 standard deviations from the mean ratio. AUCs were fine. All subjects were from the original study population. The rechallenge study was successful so the original study data was re-evaluated with n=42 (minus the 5 weirdos) and bioequivalence was concluded. How did we conclude that the 5 weirdos were enigmatic? Well their ratio observed from the rechallenge study were within ± 2 SD of the mean observed from the original study. Note that this assessment was made for Cmax and AUCs ratios.

Shouldn't it be Mean ± 3 SD as per the 68–95–99.7 rule or three-sigma rule or empirical rule????
