Figure 1. Correlation among ligand-receptor pairs.

Figure 1

(A) Correlation in ligand-receptor pairs (LRPs) in the discovery and validation datasets is largely concordant. (B) Stratified by prognosis, there is evidence of differential correlation. (C) The intersection of correlation and survival regression model interactions suggests that some LRPs are prognostic but not necessarily correlated (not autocrine).
