Quality Assessment Tools
AMSTAR stands for A MeaSurement Tool to Assess systematic Reviews.
The Jadad scale, sometimes known as Jadad scoring or the Oxford quality scoring system, is a procedure to independently assess the methodological quality of a clinical trial. Jadad et al. published a three-point questionnaire that formed the basis for a Jadad score.
This is a chapter from "Methods Guide for Effectiveness and Comparative Effectiveness Reviews."
Nonrandomised studies, including case-control and cohort studies, can be challenging to implement and conduct. Assessment of the quality of such studies is essential for a proper understanding of nonrandomised studies. The Newcastle-Ottawa Scale (NOS) is an ongoing collaboration between the Universities of Newcastle, Australia and Ottawa, Canada. It was developed to assess the quality of nonrandomised studies with its design, content and ease of use directed to the task of incorporating the quality assessments in the interpretation of meta-analytic results.
The working group has developed a common, sensible and transparent approach to grading quality of evidence and strength of recommendations.
