Figure 3. Time to first pulmonary event predicted by dysphagia etiology.
Univariate Kaplan Meier analysis of dysphagia patients grouped into seven etiologies (according to table II) and assessed for time to first pulmonary event (in months) showed statistically significant differences between groups, with patients in the Stroke group at lowest risk, and patients in the Dysphagia NOS, Esoph, and Surgery groups at highest risk (P = 0.01).
