a

Model includes age and adjustment for pathologic grade.

b

The multivariate analysis column contains empty cells because only variables with p<0.05 on univariate analysis were tested in the model.

c

Bolded values represent those significant at p<0.05.

d

Obese = BMI ≥ 30 kg/m2; Non-obese = BMI < 30 kg/m2

Abbreviations: CRS = cytoreductive surgery, BMI = body mass index, EBL = estimated blood loss
