Male circumcision for prevention of homosexual acquisition of HIV in men (Review)

The review employs clear inclusion criteria, and the authors conducted a comprehensive search. But although they use appropriate methods for analysis, there are some limitations. Of greatest importance, the evidence included in the review is described as ‘observational’, but, as the authors note, they do not assess confounding, which is the principle source of bias in this evidence, adequately. The authors acknowledge the limitation of the evidence, and they do not draw any strong policy conclusion. http://onlinelibrary.wiley.com/doi/10.1002/14651858.CD007496.pub2/pdf
