It would have been had that been the only problem with the study. See the comments by myself, Dr Steve Hickey, Len Noriega etc here http://www.cochranefeedback.com/cf/cda/feedback.do?DOI=10.1002/14651858.CD007176&reviewGroup=HM-LIVER

Meta-analyses in general are not to be trusted - at all...

I, too, would like to hear more about the problems of meta-analysis in general. So far it's naively seemed to me that they'd be more reliable than isolated studies, because they pool a larger amount of results and thus reduce the effect of chance / possible flaws or artifacts in the individual studies.
