Establishment and Validation of a Predictive Model for Radiation-Associated Aspiration Pneumonia in Patients with Radiation-Induced Dysphagia after Nasopharyngeal Carcinoma

Figure 1

Nomogram to predict 1- and 3-year PFS rates. Points were assigned for Kubota water drinking test, of the GTVnd, neutrophil count, and ESR level by drawing a line upward from the corresponding values to the “Points” line. The sum of these four points, plotted on the “Total points” line corresponds to predictions of 1- and 3-year PFS. Abbreviations: PFS: pneumonia-free survival; of the GTVnd: the maximum radiation dose of lymph node gross tumor volume; ESR: erythrocyte sedimentation rate; RAP: radiation-associated aspiration pneumonia.
