a

Studies are supplemented by data from the Cochrane systematic reviews Hunter 2007123

b

Both studies report randomisation method and allocation concealment but neither study reports masked outcome assessment and there was serious attrition from one study321. Although there is no statistical heterogeneity, differences between studies are noted in timing, intensity and duration of sessions, treatment duration and amount of supplementary written and verbal information provided.

c

All patients underwent prostatectomy for localised prostate cancer and are likely to experience more severe incontinence as a result of surgery compared to men with overactive bladder or those following a TURP. However this is unlikely to significantly reduce the applicability of the results.

d

Confidence intervals cross MID making estimate of effect uncertain.
