  1. B beta coefficient, SE standard error, RR relative risk, 95 % CI 95 % confidence interval, R0 complete cytoreduction, R0.5 cut-off point of residual disease in overall all was 0.5 cm, ASA American Society of Anesthesiologists, ECOG Eastern Cooperative Oncology Group
  2. aLogistic regression analysis
  3. b Variable “surgical team” was the most significant determinant of surgical outcomes, but it was not included into this model
  4. c It is a variable found in surgery, but interestingly, it is a predictor of complete cytoreduction not the predictor of small residual disease of 0.5 cm, so it was included in the Logistic regression model
