Adjusted hazard ratios of major cardiovascular diseases associated with per 10 μg/m³ increase in PM_2.5 concentrations. The black boxes represent hazard ratios (HRs), with the size inversely proportional to the variance of the logarithm of the HRs, and the horizontal lines represent 95% confidence intervals(CI). The arrows represent a negative HR < 1 and its 95% CI. Notes for models: Unadjusted model*Adjusting for age and sex only. Model 1**Adjusting for age, sex, active smoking status, passive smoking status. Model 2*** Adjusting for age, sex, active/passive smoking status, education, BMI, self-rated health, alcohol consumption, physical activity, household income, solid fuel used for cooking/heating. Model 3**** Adjusting for age, sex, active/passive smoking status, education, BMI, self-rated health, alcohol consumption, physical activity, household income, solid fuel used for cooking/heating, ozone and temperature.
