Mortality rates are per 100 000 person-years. Cox proportional hazards regression models use age as the time scale and are adjusted for sex, human immunodeficiency virus transmission risk group, race/ethnicity, time-dependent AIDS status, and attained calendar year. The population-attributable fraction (PAF) is calculated as PAF = pd × [(HR − 1)/HR], where pd is the proportion of deaths preceded by a cancer diagnosis and HR is the adjusted hazard ratio for the association between cancer diagnosis and overall mortality. The sum of cancer-specific population-attributable fractions approximates the fractions for all sites combined and for AIDS-defining and non–AIDS-defining cancer categories, which were estimated using separate models.
