FIGURE 2 Distribution of Cancer and Leukemia Group B Patients applying the functional operability (FO) algorithm. *VO2 corrected for body mass in kilograms (ml/min/kg). FEV1, forced expiratory volume in 1 second; ppo, predicted postoperative; DLCO, single breath diffusion capacity; VO2, oxygen consumption; VO2 max, maximal oxygen consumption.
