    ObjectiveTo assess the effect of flavonoids on chronic prostatitis, a meta-analysis of randomized controlled trials was performed.MethodsThrough using subject word and random word, PubMed, Scopus, Web of Science, and Cochrane Library were searched for related records up to July 2018. The response rate and National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) were used to evaluate the therapeutic efficacy of the flavonoids. The Cochrane handbook for systematic reviews of interventions version was used to evaluate the quality of included studies. The model of determining odds ratio (OR) was chose according to the value of I2.ResultsA total of 11 studies involving 975 subjects (experiment 516, control 459) were included. The overall OR of response rate was 0.31 (95%CI 0.11-0.89, P = 0.03). At the subgroup analysis, the OR of response rate of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) was 0.57 (95%CI 0.18-1.77, P = 0.33), while the OR of response rate of chronic bacterial prostatitis (CBP) was 0.08 (95%CI 0.02-0.33, P = 0.0005). The OR of response rate of CP/CPPS (control was placebo) was 0.29 (95%CI 0.16-0.52, P < 0.0001). The overall OR of baseline NIH-CPSI was -0.1 (95%CI -0.61-0.41, P = 0.70). The overall OR of posttreatment NIH-CPSI was -6.96 (95%CI -8.32∼ -5.60, P < 0.00001).ConclusionsThis meta-analysis indicates that the flavonoids may be clinically beneficial through significantly improving the response rate and NIH-CPSI in chronic prostatitis patients and short-lasting antibiotics therapy in association with the flavonoids could be a better choose for CBP. Moreover, the flavonoids therapy has an excellent safety profile with minor adverse effects.Copyright © 2019 National Medical Association. Published by Elsevier Inc. All rights reserved.
