Exposure-response relationships of long-term NO₂ exposure with 12 specific causes of disease incidence in the main models

Solid lines represent HRs and shaded areas represent 95% CIs. All models were stratified by age-at-risk (in 1-year scale), ten study areas, and sex, and were adjusted for education, household income, smoking status, alcohol intake, cooking fuel type, heating fuel type, self-reported health status, BMI, physical activity level, temperature, and relative humidity. The bottom panel shows the number of incident cases of the 12 specific endpoints across three ICD-10 chapters. HR=hazard ratio. NO₂=nitrogen dioxide.
