Summary of P Values (Log-Rank Test) of Prediction of Biochemical Recurrence on Training and Validation Sets

Dataset	Combined		Clinical information only
	mRNA panel	mRNA/miRNA panel
Training
All cases (n = 61)	<0.001	<0.001	0.096
Gleason score 7 (n = 42)	<0.001	<0.001	0.641
Validation
All cases (n = 35)	0.010	0.013	0.020
Gleason score 7 (n = 19)	0.027	0.010	0.028

Prediction of biochemical recurrence for the entire dataset and the subset of Gleason score 7 cases was made using two biomarker panels adjusted for T-stage, PSA, and Gleason score, or using clinical information only. Significant P values are indicated in bold.
