Note. Age = range or mean years of age of sample.

For each study, symbols indicate positive (+), negative (−), or nonsignificant (0) associations between susceptibility and another MRI measure. Studies are sorted by the secondary MRI measure that was examined.

FC = frontal cortex; TC = temporal cortex; PC = parietal cortex; OC = occipital cortex; CN = caudate nucleus; PT = putamen; GP = globus pallidus; RN = red nucleus; SN = substantia nigra; TH = thalamus; HC = hippocampus; AM = amygdala; Aβ = amyloid beta; WMH = white matter hyperintensities; FA = fractional anisotropy; BOLD = blood oxygen level dependent; PV = periventricular; conn = connectivity.

^*Data presented are averaged across all participants.
