Having surveyed the history and methods of meta-regression in a previous paper, in this paper, we review which and how meta-regression methods are applied in recent research syntheses. To do so, we reviewed studies published in 2016 across four leading research synthesis journals: Psychological Bulletin, the Journal of Applied Psychology, Review of Educational Research, and the Cochrane Library. We find that the best practices defined in the previous review are rarely carried out in practice. In light of the identified discrepancies, we consider how to move forward, first by identifying areas where further methods development is needed to address persistent problems in the field and second by discussing how to more effectively disseminate points of methodological consensus.
