CHD Deaths by Country, Age, and Sex

Data on country‐, age‐, and sex‐specific CHD mortalities were obtained from the 2010 Global Burden of Diseases study.1 Briefly, causes of death were collected in 186 countries from 1980 to 2010 based on vital registration, verbal autopsy, mortality surveillance, population census, surveys, hospital and police records, and mortuaries; completeness, diagnostic accuracy, missing data, stochastic variations, and probable cause of death were assessed (Table 1). CHD mortality was estimated using statistical modeling strategies including different permutations of covariates. Model performance was assessed with rigorous out‐of‐sample testing of prediction error and the validity of the 95% uncertainty interval (UI). CHD death was defined as International Classification of Diseases, 10th revision, codes I20–I25.
