Table 2. Weighted summary statistics of data extracted from each paper by repeat biopsy strategy.

Strategy (no. studies) [no. patients]	TP-B (14) [1756]	TS-B (12) [1987]	MRI-B (20) [914]	Overall (46) [4,657]
Mean Age (years)	64·9	63·8	64·0	64·3
Mean PSA (ng/L)	11·0	9·0	10·6	10·1
Mean No. previous biopsy episodes ^‡	1·5	1·8	1·9	1·7
Mean No. Cores at repeat biopsy	30·4	24·0	9·8	24·8
Cancer Detection Rate (%)	36·8	30·0	37·6	34·0

For the studies that do not report the mean number of biopsies, the median was used instead where possible. (TP-B – Transperineal biopsy, TS – B, Transrectal saturation biopsy, MRI-B – MRI guided biopsy).
