  1. Absolute values for cognitive function tests per tertile of MTR peak height are shown (mean [minimum - maximum]). P-values and unstandardized β are shown for general linear model multivariate analysis, adjusting for age, sex, education, systolic and diastolic blood pressure, body mass index, smoking, history of vascular disease, individual total white matter lesion load, and brain atrophy
  2. Stroop Stroop test, time in seconds to complete test, PWLT Picture Word Learning Test, number of items correctly recalled in immediate or delayed condition. LDCT Letter Digit Coding Test, number of correct digits
