概要	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.	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.
