In this network meta- analysis , we demonstrated that SeR did not show clinical ly meaningful improvement in LUTS and PF .
PATIENT SUMMARY In the present study , we found no clinical ly meaningful improvement of Serenoa repens for the treatment of lower urinary tract symptoms/benign prostatic enlargement .
CONTEXT International guidelines do not make any specific recommendations on Serenoa repens ( SeR ) for the treatment of male lower urinary tract symptoms ( LUTS ) secondary to benign prostatic enlargement ( BPE ) , due to product heterogeneity and method ological limitations of the published trials and meta-analyses .
OBJECTIVE We aim ed to compare the clinical efficacy of hexanic extract of SeR ( HESr ) versus non-HESr ( nHESr ) versus placebo versus alpha-blockers ( ABs ) in patients affected by LUTS secondary to BPE through a network meta- analysis method .
Safety and efficacy of doxazosin in benign prostatic hyperplasia: a pooled analysis of three double-blind, placebo-controlled studies.
OBJECTIVES To present the results of a pooled analysis of three double-blind , placebo-controlled studies of doxazosin in benign prostatic hyperplasia ( BPH ) . Heterogeneous symptom and bother score data collected using different symptom indices were transformed to enable a comparison of the data and to conduct a pooled , in-depth analysis . METHODS Urinary flow rates , and symptom and bother score data were shown by analysis of covariance methods to give consistent estimates of the efficacy of doxazosin across different studies , thus confirming the validity of pooling the results . Prior to analysis , symptom and bother score data were transformed so that all scales started from zero ( least symptoms or bother ) and were expressed as a percentage of the maximum score . RESULTS Doxazosin produced a significantly greater improvement than placebo in peak urinary flow rate ( P = 0.0017 ) , symptom severity ( P < 0.0001 ) , and bother caused by symptoms ( P < 0.0001 ) . Stratification showed that a greater improvement was obtained during doxazosin treatment by those with more severe symptoms at baseline ( P = 0.0001 ) . Stratification by age showed that age did not affect the capacity to benefit from treatment . Analysis of the pooled peak flow-rate data showed that doxazosin produced a consistently greater increase in flow compared with placebo . Doxazosin was well tolerated , with 10 % of patients having withdrawn due to adverse events versus 4 % with placebo ( P < 0.05 ) . CONCLUSIONS Doxazosin is well tolerated and effective in the treatment of BPH . Pooling of data has enabled more extensive and robust conclusions to be drawn than was possible for each one of the individual three studies
