Systematic reviews--triumph of form over substance?
Cochrane systematic reviews are conducted to identify level 1a evidence. So far the ENT group have published 24 reviews, while around 70 titles are in various stages of the review process. Only one review has been able to produce Ia evidence and the rest recommended further trials. The majority of otorhinolaryngology reviews are unable to identify level 1a evidence due to the paucity of high quality randomised control trials. This presents a challenge, therefore - to identify and discuss alternate methods of evidence gathering for future research?
