Comparisons of event-free survival and maintenance of Child-Pugh class after hepatectomy between patients with preoperative AT VO₂ ≥11.5 ml/min/kg and <11.5 ml/min/kg. (A) Event-free survival. The survival rate was significantly higher in patients with preoperative AT VO₂ ≥11.5 ml/min/kg (solid line) than AT VO₂ <11.5 ml/min/kg (dotted line) (p = 0.0266). (B) Maintenance of Child-Pugh class. The rate of maintenance of Child-Pugh class was significantly higher in patients with preoperative AT VO₂ ≥11.5 ml/min/kg (solid line) than AT VO₂ <11.5 ml/min/kg (dotted line) (p = 0.0464). The numbers of patients at risk are shown below each graph. AT VO₂ anaerobic threshold oxygen consumption.
