The guideline development process is characterized by the combination of formal evidence-search, formal consensus, logic (algorithms), decision and outcome analysis, and interdisciplinary development with the cooperation of 15 German and Austrian medical societies. [Table 1] shows the relationship between levels of evidence, consensus, and resulting recommendation grades of the recommendations of this guideline. The recommendation grades A – D are added to the recommendations in the abridged version. For the evidence levels, see the full version [1].
