Although final decisions are always editorial, they are greatly facilitated by the deeper technical knowledge, scientific insights, understanding of social consequences, and passion that reviewers bring to our deliberations. For these reasons, the Editors-in-Chief and staff of the journal warmly thank the 219 reviewers whose comments helped to shape Systematic Reviews, for their invaluable assistance with review of manuscripts for the journal in Volume 3 (2014).2015-11-19enMoher et al.; licensee BioMed Central.
