Model 2† (n = 602)	0.026 (0.012, 0.041) (<0.001)	0.087 (0.049–0.125) (<0.001)
HVs
Model 1* (n = 602)	0.019 (−0.002 to 0.040) (0.07)	0.066 (0.011–0.121) (0.02)
Model 2† (n = 602)	0.020 (−0.003 to 0.043) (0.08)	0.072 (0.012–0.131) (0.02)

^*Adjusted for total brain volume, age, mean glucose level, current or former cigarette smoking.

^†Adjusted for patient age, race, sex, BMI, current or former cigarette smoking, current or former alcohol use, total brain volume, history of hypertension, diabetes, heart failure, or myocardial infarction, the mean systolic blood pressure, mean LDL, mean HDL, and mean glucose levels, and use of aspirin, antihypertensive medication, or cholesterol medications. HV, hippocampal volume; PHV, parahippocampal volume; BMI, body mass index; CI, confidence interval.
