Epstein [36] | Postoperative survival | Significant predictor | Non-survivors more likely to have a < 60% predicted (p = 0.04). Non-survivors more likely to have a combined < 60% and a -AT < 50% predicted (p < 0.01). | Postoperative survival | Significant predictor | Non-survivors more likely to have a -AT < 50% predicted (p = 0.03) |

Forshaw [37] | Postoperative complications | Significant predictor | Significantly different between patients who did or did not experience postoperative cardiopulmonary complications (p = 0.04) | Postoperative complications | Not a significant predictor | No significant difference between the AT of the complications and non-complications group (p = 0.07) |

McCullough [38] | Postoperative complications | Significant predictor | Complications occurred in 16.6% of patients with a peak < 15.8 ml.kg^{−1}.min^{−1} and in only 2.8% of patients with a peak > 15.8 ml.kg^{−1}.min^{−1} (univariate odds ratio 6.77 (95% CI 1.14–51.76) p = 0.002). peak as a continuous variable was a significant predictor of complications (odds ratio of 1.61 per unit decrease (95% CI 1.19–2.18) p = 0.002. | Postoperative complications | Not documented/insufficient analysis | AT was not investigated comprehensively but showed a significant trend across the tertiles (p < 0.001). |

Nagamatsu [39] | Postoperative complications | Significant predictor | Significant difference between the _{2max}.m^{−2} of the complications and no complications group (p < 0.001). | Postoperative complications | Significant predictor | Significant difference between the AT.m^{−2} of the complications and no complications group (p < 0.001). |

Nagamatsu [40] | Postoperative complications | Significant predictor | _{2max}.m^{−2} was significantly lower in patients with cardiopulmonary complications (p < 0.001). | Postoperative complications | Not a significant predictor | No significant difference between the AT.m^{−2} of patients who did or did not have cardiopulmonary complications |

Nugent [41] | Postoperative complications | Not a significant predictor | No significant difference between the of the complications group (18.6 ml·min^{−1}·kg^{−1}) and the of the no complications group (21.8 ml·min^{−1}·kg^{−1}) | – | Not documented/insufficient analysis | – |

Older [42] | – | Not documented/insufficient analysis | – | Postoperative survival | Significant predictor | 18% of patients with an AT of < 11 ml.min^{−1}.kg^{−1} died of cardiovascular causes while in patients with AT of > 11 ml.min^{−1}.kg^{−1} it was 0.8%. p < 0.001 |
