  1. *The median follow-up time for incidence was 4.0 years (interquartile range, 3.8 to 4.0), and for mortality was 4.0 years (interquartile range, 3.8 to 4.0).
  2. †Incidence rate per 100 000 person-years, standardized to age distribution of person-years experienced by all residents using 5-year age categories.
  3. ††Adjusted for sex and age. For analyses stratified by sex, models were only adjusted for age. For analyses stratified by age, models were only adjusted for sex.
