Differences in a APOE ε4 genotype, b CSF total tau, and c phosphorylated tau levels between discordant and concordant patients. Abbreviations: AD, Alzheimer’s disease; APOE, apolipoprotein E; CSF, cerebrospinal fluid; MCI, mild cognitive impairment; SCD, subjective cognitive decline. Dotted lines on boxplot graphs represent clinical cut-offs for CSF total tau (375 ng/L) and phosphorylated tau (52 ng/L). Significance levels for group comparisons: *P < 0.05; **P < 0.01, ***P < 0.001
