Should authors of overviews of systematic reviews invite the authors of the systematic reviews they analyzed to re-evaluate or validate their methodological analysis?

Authors of overviews of systematic reviews are required to assess the methodological quality or risk of bias (RoB) of the systematic reviews included in their analysis [1]. This assessment can be performed with methodological tools such as A Measurement Tool to Assess Systematic Reviews [2] and A Risk of Bias Assessment Tool for Systematic Reviews [3]. There is some evidence to suggest that there is heterogeneity in the ratings allocated by the assessors of different research teams when analyzing the RoB of the same study included in different systematic reviews [4].
