First, the study search was limited to MEDLINE/PubMed, which has very limited coverage and comprehensiveness. The incomplete scope of the search strategy greatly increases the likelihood that publication bias and selective reporting undermine the meta-analysis.2 At a minimum, The Cochrane Collaboration CENTRAL Registry of Randomized Trials, EMBASE, and key international conference proceedings (eg, America College of Cardiology and American Heart Association scientific sessions) should have been systematically queried. Thus, we recommend that the authors perform additional and more thorough searches for potentially eligible studies.
