borderline significantp = 0.052
In the harmonised subsamples, a positive association between average global efficiency and latent sustained attention − borderline significant in the total non-harmonised sample ( r = 0.16, p = 0.052) − consistently reached significance across subsamples ( rs = 0.24-0.34, ps = 0.002-0.027), although the effect remained significant after correction for false discovery rate only in two out of five subsamples.
