Results for the three different normal tissue complication probability (NTCP) models used for radiation pneumonitis of grade ≥ 3 (left panel) and grade ≥ 2 (right panel). For each model, the left column shows the calculated NTCP for passive scattering proton therapy (PSPT) and intensity-modulated radiation therapy (IMRT) for all 165 patients (the dotted line indicates the ΔNTCP threshold). The right column shows the respective ΔNTCP. For grade ≥ 3, a threshold of 5% is applied, while for grade ≥ 2 the threshold is set to 10%.
