Table 3 Relative risks (RRs) and 95 % confidence intervals (CIs) of total, cardiovascular, ischemic heart disease, respiratory, and cancer mortality for an inter-quartile increases in PM2.5 and four PM2.5 components (4.54, 0.33, 1.67, 0.76, and 0.86 μg/m3 for PM2.5, EC, OC, sulfate, and nitrate, respectively) at lag 0–3 from unconstrained distributed lag models in the 5-county Denver metropolitan region from 2003 through 2007

From: The short-term association of selected components of fine particulate matter and mortality in the Denver Aerosol Sources and Health (DASH) study
