Note:

^a= Model 1: Non-adjusted Model (no covariates)

^b= Model 2: Demographically Adjusted Model (includes age and education)

^c= Model 3: Fully Adjusted Model (includes age, education, and GDS-15 scores).

For the full analytic sample analysis, NHWs served as the reference group to test the interaction of ethnicity in the association of SCD and cognition. B (SE) denotes unstandardized b-coefficient and corresponding standard error. β denotes the standardized coefficient. All variables included in the full analytic sample analysis (i.e., interaction analysis) were centered.
