RESULTS	Alfuzosin did not reduce the risk of AUR ( alfuzosin 2.1 % vs placebo 1.8 % , P = 0.82 ) but tended to reduce the risk of surgery ( 5.1 % vs 6.5 % , P = 0.18 ) ; the reduction in risk ( RR ) and 95 % confidence interval with alfuzosin was 22 ( -18 to 48 ) % ; and significantly reduced the risk of symptom deterioration ( 11.7 % vs 16.8 % ; P = 0.0013 ) ; the RR was 30 ( 10-46 ) % .\
