We examined the association between particulate matter [is less than or equal to] 10 [micro]m; ([PM.sub.10]) and hospital admission for heart and lung disease in ten U.S. cities. Our three goals were to determine whether there was an association, to estimate how the association was distributed across various lags between exposure and response, and to examine socioeconomic factors and copollutants as effect modifiers and confounders. We fit a Poisson regression model in each city to allow for city-specific differences and then combined the city-specific results. We examined potential confounding by a rectaregression of the city-specific results. Using a model that ...
