Muhtasari	JBI (Joanna Briggs Institute) Critical Appraisal Tools are a comprehensive suite of design-specific quality assessment instruments developed by the Joanna Briggs Institute (University of Adelaide, Australia) since 1998. Unlike single-tool approaches, JBI offers over 15 separate checklists tailored to RCTs, cohort studies, case-control studies, cross-sectional surveys, qualitative research, diagnostic accuracy, and economic evaluations. JBI tools are widely used in systematic reviews, particularly in healthcare, nursing, and public health.	The Newcastle-Ottawa Scale (NOS) is a widely used tool for assessing the methodological quality of observational studies (case-control and cohort designs) included in systematic reviews and meta-analyses. Developed by Wells et al. at Ottawa Hospital in 2000, it provides explicit criteria and a star-based scoring system that enables transparent, quantitative comparison of study quality across evidence syntheses.
