FIGURE 1.

Logistic dose-response models were fit to the data. Estimated probabilities of dysphonia, worsened dysphagia, and the composite event of dysphonia or worsened dysphagia increase as a function of dose. The y-axis represents estimated probabilities. Solid black curves represent the results of the models for each adverse event. Gray regions represent 95% confidence intervals. Open circles indicate actual doses for each procedure and are displayed with jitter to make identical values visible.
