  1. SCS suboptimal cytoreductive surgery, 95%CI 95% confidence interval, SEN sensitivity, SPC specificity, PPV positive predictive value, NPV negative predictive value, CT computed tomography
  2. aFor an SCS prevalence of 13.8%
  3. bCriteria for SCS: CT plus laparoscopy positive for SCS if both show a PCI of > 20
