Hospitalisation risk ratios of COPD patients after exposure to NO2 and ozone (single and multi-pollutant modelling results). Panel A (NO2) and B (O3) show the single pollutant modelling results, including mean temperature and wind speed. The results of the multi-pollutant model combining exposure to NO2, ozone, mean temperature, and wind speed are given in panels C (NO2) and D (O3). Displayed are risk ratios (RR, dots) and 95% confidence intervals (CI, whiskers) per 10 µg/m3 increase in air pollutant concentration
