Combined analysis of all samples irrespective of array platform used. Supervised classification (PAM) using the data derived from cross-platform analysis; 9 samples from HL patients, 9 samples from FL patients, and 9 samples from patients with RLN were used for analysis. For each sample the posterior probability, that is, the percentage of certainty of a correct class prediction, is plotted. The TGFβ fingerprint was used to classify (A) HL and RLN samples or (B) FL and RLN samples, respectively. The PD-1 fingerprint was used to classify (C) HL and RLN samples or (D) FL and RLN samples.
