Figure 2. Predicted probability of the independent dosimetry parameters and combined predictors for grade 2-3 xerostomia at the 1 year follow-up. (A): Predicted probability of the independent dosimetry parameters. (B): Predicted probability of the combined predictors. CPG: contralateral parotid gland. IPG: ipsilateral parotid gland. Dmean: mean dose. AUC: area under the curve.
