Table 1.

Definitions of true positive (TP), false positive (FP), false negative (FN), and true negative (TN) used for location matching.

	Positive mpMRI (PI-RADS ≥4)	Negative mpMRI (PI-RADS <4)
Significant cancer (Grade group ≥2)	TP (match between a positive mpMRI lesion and any significant cancer)	FN (significant cancer detected but negative mpMRI)
No significant cancer	FP (positive mpMRI but no significant cancer)	TN (negative mpMRI and negative for significant cancer)

mpMRI = multiparametric magnetic resonance imaging; PI-RADS = Prostate Imaging Reporting and Data System.
