Exposure–response relationships of long-term NO₂ exposure with disease incidence across 14 ICD-10 chapter-based endpoints in the main models

Solid lines represent HRs and the 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 right panel shows the number of incident cases recorded for each aggregated endpoint during the follow-up period. HR=hazard ratio. NO₂=nitrogen dioxide.
