Kaplan–Meier curve representing metastatic onset for patients stratified according to ERG (upper panel) and tumor-associated trypsin inhibitor (TATI) (lower panel) expression. Neither ERG (log rank (Mantel–Cox), P=0.681) nor TATI (log rank (Mantel–Cox), P=0.530) turns out to be a significant predictor of metastatic event.
