All models adjusted for individual (age, education, sex, race/ethnicity), neighborhood sociodemographic variables (Census based SES z-score), and a cohort indicator to adjust for secular trends. All models weighted by the product of the IPW and IPCW weights.
Expressed as a standard deviation change in the rate of decline in cognitive score associated with an IQR change in pollutant.
Expressed as a standard deviation change in the rate of decline in cognitive score associated with being APOE-ε4 positive
