What is the format for guideline recommendations?
Each guideline recommendation provides an assessment of the strength of the recommendation (strong, level 1 or weak, level 2) and the quality of evidence (A, B, C, D). The recommendation statements are followed by a short remark, Key information (Balance of benefits and harms, Quality of evidence, Values and preferences, Resource use and costs, Considerations for implementation), and a rationale. Each recommendation is linked to relevant SoF tables.
