Association between patient age and the level of ERG heterogeneity on the basis of all 125 patients (a) and on a tumor focus basis in all 317 foci (b), as well as in the subsets of tumor foci with Gleason ≤3 + 4 (c) and ≥4 + 3 (d). Chi2 p-value was calculated across all groups (ERG homogenous negative, ERG homogenous positive and ERG heterogeneous positive)
