  1. This is the risk (%) of perioperative cardiac events using the ACS-NSQIP prediction tool that was being used at the time of the MET-REPAIR study. Data shown are Kendall’s correlation coefficient for tied ranks (Tau-B)
  2. *p value < 0.05, actual value given
  3. ^None of the Kendall’s correlation coefficient for tied rank (Tau-B) values in Post Anaesthesia Care Unit (PACU) reached statistical significance
