Sammanfattning	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.	STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) is a 22-item evidence-based checklist published in 2007 by Von Elm et al. to improve the quality of reporting of cohort, case-control, and cross-sectional observational studies. Like CONSORT for RCTs, STROBE is endorsed by over 300 journals and is widely considered the reporting standard for observational epidemiological research.
