Meta-Analyses and Assessment of Their Methodological Quality. Russian Version of AMSTAR Questionnaire
Meta-analysis is often considered as the highest level evidence on the effectiveness and safety of drugs and other medical technologies; however, the methodological quality of meta-analyses and systematic reviews varies considerably, which leads to the differences of effect values and the levels of evidence of the results. In 2007, validated tool to assess the methodological quality of systematic reviews AMSTAR has been developed. It is based on the combination of many elements of the previous evaluation systems. We have translated AMSTAR into Russian and made some extra explanation. The current publication presents the Russian-language version of the questionnaire. We believe that the Russian version of AMSTAR questionnaire can be used for a more objective assessment of the evidence of medical technology.
