Figure 2. Longitudinal Swallowing Outcomes by Modified Barium Swallow (MBS) Study Graded per Dynamic Imaging Grade of Swallowing Toxicity (DIGEST) and MD Anderson Symptom Inventory–Head and Neck Module (MDASI-HN) Swallowing Symptom Severity Item Among Patients With Low- to Intermediate-Risk Oropharyngeal Squamous Cell Carcinoma.

A, Longitudinal prevalence and severity of pharyngeal dysphagia among the primary transoral robotic surgery (TORS) group per MBS DIGEST (n = 75). B, Least-square means of MDASI-HN swallowing symptom severity item adjusted for baseline item score, age, and concurrent chemotherapy (n = 219). C, Difference in prevalence of moderate to severe dysphagia (MBS DIGEST grade ≥2) at 3 to 6 months by primary treatment group. D, Prevalence of moderate to severe dysphagia (MBS DIGEST grade ≥2) at 3 to 6 months by treatment group (n = 257) and by treatment subgroup. Error bars indicate 95% CIs.
