Estimated long-term ${\mathrm{O}}_3$-exposure attributable respiratory deaths in 2010 for adults $\ge 30\mathrm{y}$ of age. Units are attributable deaths per 100,000 people, and estimates were derived using the T2016 relative risk estimate [$\text{HR}=1.12$ (95% CI: 1.08, 1.16), adjusted for near-source and regional ${\text{PM}}_{2.5}$, and ${\text{NO}}_2$ exposure] and annual average daily maximum 8-h ${\mathrm{O}}_3$ concentration as the ${\mathrm{O}}_3$ exposure metric, with a low-concentration cutoff set at the minimum exposure in the Turner et al. (2016) cohort ($26.7\text{ppb}$) (Map Data: © EuroGeographics for the administrative boundaries).
