Number of people exposed to different ranges of mean (left column) and maximum (right column) HRI of all-cause mortality, associated with the long-term exposure to PM2.5, NO2 and O3. The solid histogram bars represent the HRI calculated using the RR values provided by the WHO, the green dashed-dotted line represents the HRI calculated using the RR’s 95% CI lower limit, while the red dashed line, the one using the upper the 95% CI upper limit
