Hi nobody,

❝ Is that a new trend, to setup trial designs without checking the appropriate statistics to evaluate the results (see also 2-stage scaled BE trials)? Just asking...

No, it isn’t.
As I wrote above »I know some companies routinely applying this “method”«… At least one of them is a very (very!) big player. During two in-house trainings they didn’t believe me (“We never [sic] faced any problems in our sub­mis­sions!”).

Old beliefs die hard
even when demonstrably false.   E.O. Wilson
