Hi nobody,

❝ Found this here:

❝ https://www.ncbi.nlm.nih.gov/pubmed/28257283

❝ […] if I understand this correctly, the authors say, CVintra for Cmax is generally higher than for AUC, therefore use AUC to estimate the sample size of your study.

Ah – the formerly pink, now black journal. ;-)

❝ Did I get this right?

At least this is what the last sentence of the abstract says: “Hence, CV derived from AUC instead of C_max should be used in sample-size calculation to achieve a sufficient, yet practical, test power. ”

❝ Any thoughts on this approach?

Outright bizarre. Since the authors are of a CRO, maybe the love failed studies in order to repeat them? Do you have a copy to share?
