Numbers represent regression coefficients (standardized beta's), adjusted for age, sex, educational level, depressive symptoms, hippocampal, and WML volume and the presence of lacunar infarcts.
P < 0.05
**P < 0.01
Higher test scores reflect a less negative forgetting rate, that is, a better performance.
