aUnadjusted and adjusted odds ratio and their 95% confidence intervals (CI) were obtained from results of the binary logistic regression analysis.
bAdjusted for sex, age, and education.
STI, spectrum triangular index; MDF, median frequency; PPL, positive peak latency; CN, cognitive normal; MCI(-), mild cognitive impairment with amyloid negative and neurodegeneration positive; aAD, asymptomatic Alzheimer disease; pAD, mild cognitive impairment with Alzheimer’s pathology. The p-value of lower than 0.05 were presented in boldface.
