  1. Notes for Tables 1–3: Among 5,511 AHEAD self-respondents (at baseline) with linked Medicare claims who were not in managed care at their baseline interviews. All variables were binary coded (1 = yes, 0 = no) except total wealth (actual dollar value) and the number of health insurance policies (actual number). RG = Reference Group.
