The clinical model alone had an AUC of 0.60 (0.06). Models using EUD alone derived from clinician or auto-contours had AUCs of 0.60 (0.10) and 0.60 (0.09). AUC for models involving clinical factors and dosimetry was 0.65 (0.09) and 0.66 (0.09) when using clinician contours and auto-contours (figure 2). ΔAIC was found to be less than 2 between models using different contours.

Conclusion:
