This paper repeats the common place statement that a small p-value does
not necessarily indicate an important finding. Agreed, but maybe I
overlooked examples of important findings with large p-values.
If there are some, I would be happy to get to know some of them.
Otherwise a small p-value is no guarantee of importance, but a prerequisite.
