HC | −.286 | .0429 | −.3329 | −.2471 | −6.68 | .001 |

Note. HC – hippocampus; CD – caudate nucleus; PT – putamen; EC – entorhinal cortex; SFG – superior frontal gyrus; VC – primary visual cortex; SE – standard error; 95% CI – upper and lower confidence intervals. Slope is estimate of T2* ms slowing per calendar year.
