Fig. 3From: The role of lifestyle in the association between long-term ambient air pollution exposure and cardiovascular disease: a national cohort study in ChinaMultiplicative and additive interaction analysis of the effect of dichotomized lifestyle on the association between ambient air pollutant exposure and CVD. Model adjusted for age, sex, education, residence, alcohol consumption, and income. CI, confidence interval; CVD, cardiovascular disease; HR, hazard ratio; NO2, nitrogen dioxide; O3, ozone; PM1, particulate matter with an aerodynamic diameter less than 1 μm; PM2.5, particulate matter with an aerodynamic diameter less than 2.5 μm; PM10, particulate matter with an aerodynamic diameter < 10 μm; RERI, relative excess risk due to interactionBack to article page
