a–f, C–R curves for all-cause respiratory disease (a), asthma (b), COPD (c), AURI (d), influenza (e) and pneumonia (f). The centre of the error bands represents the mean effect estimates comparing days with lower versus higher wildfire-specific PM2.5 levels across 1,052 study communities, with error bands indicating uncertainty ranges derived from the 95% CIs of 1,000 Monte Carlo samples. All the models were controlled for temperature, relative humidity, non-wildfire PM2.5, day of week, seasonality and long-term trend.
