Note. β = standardized regression coefficient. CF = Complex Figure. Model 1: Adjusted for age, sex, education, race, and total intracranial volume. Model 2: Adjusted for Model 1 + Left and Right HV simultaneously. Model 3: Adjusted for Model 1 + Model 2 + Complex Figure–Copy. Bold indicates significant associations.
