Dose–volume histograms for PTV and OARs for two representative 50 Gy test cases: Model 1 (Patient 5, left) and the mixed‑prescription Model 4 (Patient 4, right). Solid lines indicate ground truth and dashed lines the predicted DVHs. The Model‑4 panel illustrates a case with larger spinal cord deviations compared with the single‑prescription model.
