Note: Based on 865 person—years of elderly Medicare beneficiaries with cancer and depression using Medicare Current Beneficiary Survey 2000–2005. The regression also included intercepts. The reference group for the dependent variable was “No depression treatment.” Asterisks represent significant differences in likelihood of depression treatment compared to the reference group based on multinomial logistic regression.
AOR: adjusted odds ratio; CI: confidence interval; Sig: significance; LT: less than; HS: high school; high school; ADL: activity of daily living.
