Dear Ohlbe,

❝ Well, cough... I your example there is not much difference for AUC, agreed. But Cmax ? A difference of 4 points in the point estimate, …

Actually 5.9%!

❝ … closer to 1 with the lousy method, with 90 % CI of 78.6 - 99.8 % with the lousy method against 71.1 - 96.4 % with the good method... In this specific example I would say that yes, it could have mattered, and made a difference between a failing study and a passing study !

Agreed. I guess the difference would have been smaller if we didn’t stop the LC/MS-MS method after 12 subjects (in the good ol’ days of plausibility reviews). The lousy method was validated and all batches passed. Nowadays such a method likely would not survive the ISR.
