AMSTAR (A MeaSurement Tool to Assess systematic Reviews) has been developed by Shea et al. in 2007 [1] to assess the methodological quality of systematic reviews and meta-analyses (MA). In 2017, Shea et al. proposed a revised version of this tool [2]. Recently, Lorenz et al. [3] published, in this journal, an important article in which they confirmed the validity of this revised tool and highlighted the moderate inter-rater reliability (IRR) of AMSTAR 2 in a sample of 60 MAs published between 2012 and 2017 in the field of depression.
