概要	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.	The Critical Appraisal Skills Programme (CASP) RCT Checklist is a practical, widely adopted tool developed by the UK-based Critical Appraisal Skills Programme (founded 1993) for assessing the methodological quality and relevance of published randomized controlled trials. Unlike numeric scoring scales, it uses 11 structured questions with yes/no/cannot tell responses to guide critical appraisal in a format accessible to busy clinicians, researchers, and educators.
