Figure 1: Extended minimal spanning tree of bivariate features predicting prostate cancer PSA recurrence after redical prostatectomy. Node size is proportional to –log 10 (univariate log-rank test P-value), the edge size is proportional to –log 10 (bivariate log-rank text P-value). A missing arrow head represents a c1 (or c2) = 1 in the bivariate combination of two features
