*

Unadjusted means or percentages reported at baseline. At 24 months, means/percentages are adjusted for chronic disease score, self-reported health, age, sex, and baseline value of outcome if available (physical function, bed and restricted-activity days, HbA1c and cholesterol, use, and costs).

P based on comparison of log costs. CES-D, Center for Epidemiological Studies Depression scale.
