Statistical significance was computed using Pair-Samples T-Test, with a significance level of p < 0.05.

Statistical significance was computed using the Fasano & Franceschini test for separation of principal components and the hypergeometric probability formula for significance of overlap in gene signatures.
This result is a good example that significance measures can be used as a clever mechanism to prune motifs not only after, but also before, their significance is computed.
The significance was computed by permutation of group membership, with 10,000 replicates.
Statistical significance was computed using non-parametric methods and the method of closed testing procedure (Kruskal Wallis and Mann–Whitney U test).
RDA and the tests of significance were computed using the functions 'rda' and 'anova.cca' from the 'vegan' library [21] of the R statistical language [22].
The significance is computed by permutation of group membership (n = 10000) and results are provided using a post-hoc test (Bonferroni).
After 10,000 permutation trials, the overall significance was computed as the fraction of the time the suprathreshold area was greater in the randomized maps than the real effect [52].
