Table 3.

Treatment outcome with respect to radiation pneumonitis (RP) for patients predicted to benefit from proton therapy treatment using the model-based approach. The number of patients enrolled by the model-based approach are listed. The modality that these patients received in the original trial: intensity-modulated radiation therapy (IMRT) and passively scattered proton therapy (PSPT) is listed and the grade of RP these patients experienced.
