* The values listed in this category implicate the classification for all high-grade PCa tissue group against non-cancer tissue types (nPZ and BPH). ** The values listed in this category implicate the classification for each PCa tissue group (e.g., GS 9) against remaining tissue groups. All are high grade (GS≥7).
