Notes: Rows represent separate regression analyses adjusting for the sample-specific demographics (age, sex, and education). For sex-stratified results, ♂ indicates instances where the predictor was significant among men; ♀ indicates instances where the predictor was significant among women (p < .05). No symbols indicate that the variable was not significant in either sex-stratified analysis. Shaded areas denote when a variable was not available for this cohort. β reflects the standardized beta coefficient. APOE = apolipoprotein; MMSE = Mini-Mental State Examination; SE = standard error.
