↵a R2 is the adjusted R2 representing the proportion of variation in white matter hyperintensity volume explained by all variables in the model, corrected for the number of variables—model 1: adjusted for total brain volume; model 2: adjusted for total brain volume, age, antihypertensive use, brain parenchymal fraction, and transit time.
