Notes: Numbers in parentheses are 95% confidence intervals. The data are for both sexes combined. The model adjusts for sociodemographic characteristics (age, sex, race/ethnicity, and marital status), socioeconomic status (education, income, and wealth), and associated behaviors (smoking and physical activity). Time is used as x-axis variable. The data are weighted except for sample size and number of deaths.
