Figure 1 Kaplan-Meier survival curves using both PkVO2 of 14 ml/kg/min and PkVO2 lean of 19 ml/kg/min as cutoffs showing a stronger prognostic value to the fat-adjusted PkVO2 by log-rank testing. PkVO2 = peak oxygen consumption; PkVO2 lean = peak oxygen consumption adjusted to lean body mass; VO2 = oxygen consumption.
