Table III. Joint association of life-space mobility restriction (LSR), defined as life-space mobility score <60, and peripheral artery disease (PAD) with all-cause mortality.

Model 1: Unadjusted model showing the association of PAD and life-space restriction with all-cause mortality.

Model 2: Model adjusting for all covariates including demographics, diabetes, hypertension, coronary artery disease, stroke, kidney disease, chronic obstructive pulmonary disease, congestive heart failure, gout/arthritis, Geriatric Depression Scale score, and Mini-Mental State Examination score.
