    PREVENT III (PIII) critical limb ischemia (CLI) risk score was an effective tool for discriminating three significant strata of risk when tested on the following endpoints: perioperative major adverse cardiac event (MACE) (a), perioperative and 1-year mortality (b), and 1-year ability to ambulate (c).
