2024 amstar 12 The 12 items of the AMSTAR 12 are as follows: 1. Was an "a priori" design provided? 2. Was there a duplicate process for study selection and data extraction?
10. Was the likelihood of publication bias assessed? 11. Was the conflict of interest included? 12. Was the supporting documentation provided? Each item of the AMSTAR 12 is rated on a 4-point scale (yes, partial yes, no, or cannot answer). The overall score of a systematic review is calculated by summing up the number of "yes" responses and dividing it by the total number of items. The score ranges from 0 to 12, with a higher score indicating a better methodological quality. The AMSTAR 12 is a valuable tool for assessing the quality of systematic reviews, and it can be used to identify areas for improvement in the review process. It can also be used to compare the methodological quality of different reviews and to inform the decision-making process in evidence-based medicine. The AMSTAR 12 is a revised version of the original AMSTAR tool, which was published in 2007 and consisted of 11 items. The new version includes updated and refined criteria to better reflect the current standards of systematic review methodology. The AMSTAR 12 is a validated and reliable tool that has been widely adopted in the research community.
2. Was there a duplicate process for study selection and data extraction? 3. Was there a comprehensive literature search? 4. Was the status of publication (i.e. grey literature) used as an inclusion criterion? 5. Was a list of studies (included and excluded) provided? 6. Were the characteristics of the included studies provided? 7. Was the scientific quality of the included studies assessed and documented? 8. Was the risk of bias from individual studies included in the review reported? 9. Were the methods used to combine the findings of studies appropriate? 10. Was the likelihood of publication bias assessed? 11. Was the conflict of interest included? 12. Was the supporting documentation provided?

It can also be used to compare the methodological quality of different reviews and to inform the decision-making process in evidence-based medicine. In conclusion, the AMSTAR 12 is a comprehensive and reliable tool for assessing the methodological quality of systematic reviews. It is widely used in the research community and has been validated in various studies. By using the AMSTAR 12, researchers and clinicians can ensure that the systematic reviews they use are of high quality and provide reliable evidence to inform their decisions.
