Dear Helmut,

Regarding 6x3 crossover design (with one treatment T and two references R1 and R2), I learned that “Two‐at‐a‐Time Principle” is superior most of time than Pooled ANOVA. Would you evaluate the advantages of two independent 2x2 trials (T vs. R1 and T vs. R2) over the 6x3 crossover design? Actually I have completed the two 2x2 trials. However, someone has challenged me for not conducting it as in 6x3 crossover. Could you please help?

Many thanks,

A central lesson of science is that to understand complex issues
(or even simple ones), we must try to free our minds of dogma and
to guarantee the freedom to publish, to contradict, and to experiment.
