Snippet: • First, we repeat all the analyses using alternative methods to estimate exposure to PM 2.5 . 26 • Second, because our study relies on observational data, our results could be sensitive to modeling choices (e.g., distributional assumptions or assumptions of linearity). We evaluate sensitivity to such choices by conducting analyses: ○ Treating PM 2.5 as a categorical variable (categorized at empirical quintiles) ○ Adjusting for population.....

We evaluate sensitivity to such choices by conducting analyses: ○ Treating PM 2.5 as a categorical variable (categorized at empirical quintiles) ○ Adjusting for population density as a categorical variable (categorized at empirical quintiles) ○ Using a negative binomial model without accounting for zero-inflation.
