Note: Multiple linear regression with the forward stepwise method: R squared = 0.374, F (2, 32) = 9.559, p = 0.001.
WMH: white matter hyperintensity; nWMH: normalized total WMH volume; nHippocampus: normalized hippocampus volume; APOE: apolipoprotein E; CDR-SB: clinical dementia rating-sum of boxes. Multiple linear regression with the enter method: R squared = 0.540, F (8, 26) = 3.821, p = 0.004.*p < 0.05.
