Medicare LDS 2003‐2014: Data Used. Continuously enrolled fee‐for‐service Medicare beneficiaries who were age 65 in years 2003 to 2008, and as of January 1, 2011 had no evidence of cognitive impairment were included in the analysis. Exclusion criteria (any claims with diagnostic codes reflecting a dementia diagnosis) were applied through the end of 2010. Years 2011 and later were included in the discrete‐time survival analysis. Beneficiaries were followed until 2014 if the beneficiary survived without dementia, or until the year of dementia diagnosis or death
