Note: Models were adjusted for clinical group, age, gender, race, living arrangement, education, and net worth (Referent groups: Clinical Group, Relatively Healthy; Age, 51–64 years old; Gender, Male; Race, Caucasian; Living Arrangement, Married; Education, <12 years; Net Worth, ≤40,000 dollars). Model 2 included age group—clinical group interaction terms (referent group: 65–75 years old—Relatively Healthy Group). Model 3 was also adjusted for use of insulin (referent group: No).
Hazard ratios were derived using Health and Retirement Study respondent population weights to adjust for differential probability of selection into the sample and differential nonresponse.
