Associations between cardiorespiratory outcomes and O 3 and PM 2.5 by visit type. Displayed risk ratios are the exponentiated sum of the coefficients for lags 0–4 from distributed lag models. Risk ratios are computed per interquartile range of pollutant concentrations (27.3 ppb for 8-hr maximum O3; 9.3 μg/m3 for 24-hr average PM2.5). RR: risk ratio, IQR: interquartile range, O3: ozone, PM2.5: particulate matter ≤2.5 micrometers in diameter, RD: respiratory disease group, CVD: cardiovascular disease group, CHF: congestive heart failure, ED: emergency department, HA: hospital admission.
