Exact excerpt

Using an instrumental variable design and combining air quality data with a bibliographic dataset of publications, we found that an increase of 1 μg m−3 in the annual concentration of PM2.5 (particles smaller than 2.5 μm in diameter) causes a decline of 0.23% (P < 0.01; 95% confidence interval, −0.0028 to −0.0017) in publications.
