CRD COMMENTARY: The review is not methodologically rigorous. No study inclusion criteria, or criteria to check the validity or relevance of included studies, are given. The outcomes used are not clearly defined. Studies that are described in the results section are not included in the Tables of studies. The majority of studies reported are very small. The studies are not ordered by methodological strength and so it is difficult to untangle the level of evidence for the various findings.
