Σύνοψη	MMAT (Mixed Methods Appraisal Tool) is a practical, design-agnostic quality assessment tool developed by Pluye et al. (2014, updated 2018) to evaluate the methodological quality of quantitative (RCTs, non-randomized studies), qualitative, and mixed-methods studies. Unlike tools designed for single paradigms (e.g., Cochrane RoB 2 for RCTs), MMAT provides unified criteria applicable across diverse research methodologies, making it particularly useful for systematic reviews incorporating multiple study designs.	GRADE (Grading of Recommendations Assessment, Development and Evaluation) is a systematic, transparent framework for assessing the certainty of evidence and determining the strength of clinical recommendations in healthcare. Published in 2008 by Guyatt et al., GRADE has become the international standard for guideline development, used by the World Health Organization, Cochrane, and most major clinical guideline organizations worldwide.
