Fig 1 Associations of functional performance measures with physical activity during daily life in persons with peripheral arterial disease (n = 156).* * Functional performance across quartiles of physical activity are shown. Data adjust for age, gender, and race. Physical activity was measured continuously for seven days using a Caltrac vertical accelerometer.
