Data Extraction and Analysis
After quality appraisal, data extraction and analysis were performed by
one reviewer and checked by another one. Any discrepancies were resolved
by discussion between them and the third reviewer. The main
characteristics of these publications were extracted; this includes the
development, organization, publication year, development method, and
evidence grading system. Following that, the results of the AGREE II
appraisals, which are the standardized domain scores based on the method
mentioned above and results of the overall assessments, were compiled.
