ROC curves for all threshold values for neopterin and CXCL-13 in patients with stage 1 disease and in patients with non-stage 1 disease (intermediate stage and advanced stage 2). ROC curves represent sensitivity as a function of the complement of specificity (1 − specificity) for all threshold values for neopterin and CXCL-13 in patients with stage 1 disease (a) and in patients with non-stage 1 disease (b).
