Flinders University What is the background for this study? What are the main findings?

Response: An increase in the volume of evidence published in the peer-reviewed literature on this topic prompted an update of this Cochrane Review. What should readers take away from your report?

Cranberries, UTIResponse: This updated review of the totality of the international evidence is important because the conclusions have changed compared to previous versions of this review. In the past, the review findings were inconclusive.

However, in this newly updated review there is now double the volume of evidence and the findings demonstrate potential benefit for some people. However, it is important that people who have a UTI, or experience recurrent UTIs, seek healthcare advice to discuss whether the use of cranberry products, such as concentrated liquid, capsules or tablets, is appropriate for them. What recommendations do you have for future research as a results of this study?

Response: More research is required to determine the best dosage and modality of ingestion to get optimal therapeutic effect.
