Pathologic characteristics of men whose prostatectomy tissue was represented on the TMA sets by race^*.

^*Pooled over the PCBN lower-grade and PCBN higher-grade TMA sets. White and Black men on each TMA set were frequency matched on age, prostatectomy Gleason score, and pathologic stage.

^**Men with higher-grade disease whose prostatectomy tissue was represented on the PCBN lower-grade TMA set (n=6) were excluded because there was an insufficient number of cases to establish TMA- and high grade-specific biomarker cut-points.
