Dose volume histograms stratified by dysphagia classification (per DIGEST) 3–6 months after RT (n=97).
Abbreviations: ROIs; region of interests, ADM; anterior digastrics muscle, CPM; cricopharyngeal muscle, GGM genioglossus muscle, GHM geniohyoid muscle, (S/M/IPC); Superior/ middle/inferior pharyngeal constrictors, MHM; mylohyoid, ITM; intrinsic tongue muscle. Heatmap of statistical significance for utilized analyses, is displayed below each ROI DVH to quantify the magnitude of p-values for each 1-Gy bin, allowing visual representation of Bonferroni correction. Solid blue squares denote lack of statistical significance, while solid red squares indicate statistical significance under strict multiple-comparison correction.
