Figure 3

The ROC of PREct, PREpet, PREcombination and SUVmax, and the difference between the AUCs in these predictive variables. Abbreviations: ROC, receiver operating characteristics; AUC, area under the ROC curve; PET, positron emission tomography; CT, computed tomography; PREct, CT-predictive variables; PREpet, PET-predictive variables; PREcombination, the combination of PET and CT predictive variables; LLN, lymphomatous-lymph nodes; CLN, cancerous-lymph nodes; HLLN, LLN caused by Hodgkin’s lymphoma; NHLLN, LLN caused by non-Hodgkin’s lymphoma.
