Hi ElMaestro,

❝ I get a 26% CV for AUC, which is a bit higher than the observed CV for Cmax.


Which number-cruncher are you using? Mighty PowerTOST gives 23.9% for AUC and 20.4% for Cmax. Try:

library(PowerTOST)
round(100*CVfromCI(lower=0.83186, upper=1.0402,  n=26, design="2x2"), 1)
round(100*CVfromCI(lower=0.61796, upper=0.74855, n=26, design="2x2"), 1)

The quality of responses received is directly proportional to the quality of the question asked. 🚮
