In all cases, the post-hoc contrasts were highly significant (p-value < 1 × 10 −6 ).
In all cases, the post-hoc contrasts were highly significant (p-value < 1 × 10 −6 ).
Although the non-parametric tests used in the multiple comparisons generally yielded significant differences in all the contrasts used, in some cases, the post-hoc comparisons were marginally significant, essentially because of the low number of observations.
