Note. The 32 mediation analyses with n = 47 are listed. The hippocampal formation subfields that were associated with aerobic fitness were used as mediators between aerobic fitness and long-term memory performance.

Significant p values (<0.05) are written in bold and marked with an asterisk.

ACME average causal mediation effect, CI_low lower confidence interval, CI_high higher confidence interval, p uncorrected p value, p_fdr fdr-corrected p value.
