“…However, there was some divergence in how study authors characterized the rigor of the scoping review methodology. The terms 'systematic', 'rigorous', 'replicable', and 'transparent' were frequently used to describe the methodology, and several authors described scoping reviews to be comparable in rigor to systematic reviews (Gagliardi et al, 2009;Liu et al, 2010;Ravenek et al, 2010;Feehan et al, 2011;Heller et al, 2011).
