概要	COSMIN (COnsensus-based Standards for the selection of health Measurement INstruments) is a systematic framework and 10-item checklist developed by Mokkink et al. (2010) to evaluate the methodological quality of studies that assess the measurement properties of patient-reported outcome measures (PROMs), questionnaires, and clinical scales. COSMIN guides the development, validation, and selection of health measurement instruments across clinical research and practice.	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.
