Values are odds ratio (95% confidence interval).
Increase >50% from baseline. Participants with a >50% decrease were combined with those with <50% change. All models additionally adjusted for baseline cTnT concentration.
Demographic variables: age, sex, race (African American or other), and education (more than high school).
Comorbidities: body mass index, diabetes, hypertension, coronary heart disease, claudication, emphysema, stroke, major electrocardiographic abnormality, and self-reported health.
cTnT = cardiac troponin T; other abbreviations as in Table 2.
