Información condicional

How this model should be used:
This model predicts 1-year survival in patients with colorectal peritoneal metastases treated with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). 

Model performance: 
The COMPASS model differentiated well and showed a Harrell's c statistic of 0.72 with a calibration plot showing good agreement. The overall performance of the COMPASS as assessed with the explained variation (Nagelkerke R2 statistic) was 0.19.

Context information:
External validation of an alternative prediciton model (peritoneal surface disease severity score; PSDSS) was performed for the same dataset (200 patients with colorectal peritoneal metastasis treated with CRS + HIPEC). Discrimination of the PSDSS model was suboptimal with a Harrell's c statistic of 0.62.
