Tóm tắt	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.	RoB 2 is the Cochrane Collaboration's updated methodology for assessing the risk of bias in randomized controlled trials (RCTs). Published in 2019, it replaced the original Cochrane RoB tool with a more structured, transparent approach using signalling questions and domain-based judgments to evaluate five critical sources of bias.
