Abbreviations: abs Pcor = absolute/unsigned Pearson correlation; Dcor = distance correlation; Pcor = Pearson correlation; RA = Reliability of the age‐effects; RP = Reliability of each participant's connectivity matrix; RSB = Reliability of single between‐network connections; RSW = Reliability of single within‐network connections; SP = Similarity between participants in the same age‐range.

S0, S6, and S8 refer to the mm of smoothing that was applied to the data. Diff = difference between the two estimates, this is reported for comparisons where permutation test are used. Zval = z‐value from the Wilcoxon signed rank test; Pval = P‐value.
