Source: SEER-NLMS Record Linkage Study. Based on the 1979 through 1998 follow-up of residents of 11 SEER Registries (Iowa, Hawaii, Seattle, Connecticut, Detroit, Utah, Los Angeles, San Francisco/Oakland/San Jose/Monterey, Greater California, Louisiana, and Kentucky) who were 25 yearsof age or older on their CPS survey date

^aRates are per 100,000 population and are age-adjusted to the 2000 US standard population by the direct method

^bRate ratios were estimated from Cox regression models that stratified for age at survey and CPS cohort and controlled for sex when relevant
