Prediction of Grade 3 Esophagitis Based upon 126 Patients with Measured Cytokines from Four Models Using Increasing Amounts of Clinical and Cytokine Data

	Dose = D2cc		Dose = gEUD
	AUC	Log Likelihood	AUC	Log Likelihood
Dose only	0.750	−37.7	0.727	−37.7
Dose + clinical	0.779	−37.1	0.768	−37.2
Dose + clinical + Cyt0	0.758	−37.8	0.735	−37.6
Dose + clinical + Dose*Cyt0	0.773	−37.4	0.749	−37.5

The model with the largest log-likelihood (in bold) was selected.

Cyt0, pretreatment cytokine levels.
