Table 4 –

Total number of biopsies performed and avoided if performing biopsy only for a positive change in MRI (PRECISE scores ≥4) at 2-yr follow-up.

Biopsy threshold	Progression endpoints	Total biopsies, N	Total progressed, N (%)	Performed biopsies, N	Avoided biopsies, N	Missed progression in avoided biopsies, N (%)

Positive change in MRI	GG1–>GG2	194	55 (28.4)	85	109	24 (22)
	GG1–>GG3	194	16 (8.25)	85	109	4 (3.7)
	GG2–>GG3	78	26 (33.3)	38	40	9 (22.5)

GG = Gleason grade group; MRI = magnetic resonance imaging; PRECISE = Prostate Cancer Radiologic Estimation of Change in Sequential Evaluation.
