All continuous numerical data are presented as mean±SD [subgroup with data available]. WMH volume was normalized by total brain volume and natural log-transformed prior to further analysis. MCI indicates whether patients were considered to have mild cognitive impairment as opposed to being cognitively unimpaired. Race indicates patients’ self-reported race, while ethnicity indicates whether patients reported being of Hispanic or Latino ethnicity. MCI, mild cognitive impairment; PET, positron emission tomography; SUVR, standardized uptake value ratio; WMH, white matter hyperintensity.
