DR = delayed recall; IR =  immediate recall; r = correlation coefficient. Analysis adjusted for age, sex, education, APoE  ε4 status and total intracranial volume. Bootstrap results are based on 5000 bootstrap samples. P-values in bold survived FDR correction for multiple comparison at P_FDR < 0.05 using Benjamini-Hochberg criterion (α = 0.05).

*P_FDR < 0.05.

^a Uncorrected P < 0.05.
