Association expressed in Hazard Ratio (95% Confidence Interval(CI)) with referent as 6 MWT distance Quintile>414 meters.

Models stratified by either age, gender or race and adjusting for all other covariates including general health status, education level, smoking status, systolic blood pressure, total cholesterol, fasting glucose, C-Reactive Protein, body mass index, prevalent medical conditions (pulmonary disease, diabetes mellitus, arthritis), any difficulty in Activities of Daily Living or Instrumental Activities of Daily Living, CES-Depression scale score, Modified Mini-Mental State score, major electrocardiogram abnormalities, ankle-brachial index, and medication use (aspirin, any lipid lowering, any anti-hypertensive).
