Combining aggregate and individual-level data to estimate individual-level associations between air pollution and COVID-19 mortality in the United States
Table 6
Summary of COVID-19 mortality odds ratios (OR) and 95% credible intervals (CI) for a 1 μg/m3 increase in PM2.5 from sensitivity analyses based on 1) changing the number of age groups used for stratification, 2) using fixed versus estimated offsets for strata-specific odds ratios, and 3) estimating PM2.5 aggregated to the county-level or census tract-level.
The first row represents our main analysis.
