Epidemiologic studies have reported associations between fine particles (aerodynamic diameter <2.5 Jim; PM2.5) and mortality. However, concerns have been raised regarding the sensitivity of the results to model specifications, lower exposures, and averaging time. This study addressed these issues using 11 additional years of follow-up of the Harvard Six Cities study, incorporating recent lower exposures.
