The Kalbfleisch and Prentice approach: prostate cancer risk by stage at diagnosis. Hazard rate ratios for the effect of prostate cancer diagnosis on Alzheimer’s disease estimated using Cox regression. Models are controlling for a lagged Charlson Comorbidity Index score, familial excess longevity, religious status, obesity, smoking history, and neighborhood measures of population and median family income and stratified by birth year. Cancer diagnosis is treated as a time-varying effect.
