The correlation between summary exposure value (SEV) smoking and SEV Ambient particulate matter (AMPM) pollution with sociodemographic index, in 204 countries or territories, 2021, by sex. (where circle size represents incidence and death cases of COPD in 2021: the blue line and grey shadows represent the overall 95%CIs in age-standardized rates associated with SDI, and the dashed lines represent quantile regression estimated fit quantile/95th, 75th, 50th, 25th and 5th percentiles. The r indices and p values presented were derived from pearson correlation analysis.). * indicate the significant correlation coefficient between two variables on 0.1% level of significance. A circle represent the incident cases 2021, B circle represent the death cases 2021
