    Survival curves for all patients undergoing lower extremity bypass, as well as by indication (claudication or critical limb ischemia [CLI]). Failure is defined as death or inability to ambulate.

    Risk of not ambulating at 1 year is shown by number of risk factors present. The light bars represent the predicted value from the model, and the dark bars represent the actual observed values.
