Extended Data Fig. 1: The respiratory hospitalization risks associated with a 1 µg/m3 increase in wildfire-specific PM2.5 over the lag 0–7 days.
From: Respiratory risks from wildfire-specific PM2.5 across multiple countries and territories

The center of the error bars represents the mean effect estimates comparing days with lower versus higher wildfire-specific PM2.5 levels across 1052 study communities, with error bars indicating uncertainty ranges derived from the 95% CIs of 1,000 Monte Carlo samples. The models controlled for temperature, relative humidity, non-wildfire PM2.5, day of week, seasonality and long-term trend. Abbreviations: PM2.5, particulate matter with diameter ≤ 2.5 µm; CI, confidence interval.
