| 20 October 2014 | New citation required but conclusions have not changed | We identified no new studies for inclusion in the review. One study is ongoing (Saedi 2007). There were no changes to the conclusions of the review. We updated the study quality assessment method to the Cochrane 'Risk of bias' tool. We updated the 'Background', 'Discussion' and 'Implications for practice and research' sections to reflect current clinical practice and the decisions that patients and practitioners have to make in 2014. |
