Rate is per 100 person-years.
Rate ratios for individual outcomes were estimated from a Cox proportional hazards regression stratified on age, sex, and state of residence, and adjusted for race, Charlson comorbidity score, number of medications used, physician visits, days in hospital, and days in nursing home during the baseline period, and history during the baseline period of chronic obstructive pulmonary disease, obesity, stroke or transient ischemic attack, hypertension, congestive heart failure, atrial fibrillation, dementia, depression, liver disease, rheumatoid arthritis, osteoarthritis, hip fracture, and cancer (model 2). Rate ratios for composite outcomes were estimated using a Poisson regression adjusted for the same covariates.
Prostate specific antigen test, fecal occult blood test, and mammography analyses were restricted to subjects without a history of the cancer detected by the screening test. Bone mineral density testing analysis was restricted to women without a history of hip fracture.
