^aLogistic regression analysis
^b Variable “surgical team” was the most significant determinant of surgical outcomes, but it was not included into this model
^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
