Evidence
Scientific proof. How robust it is depends, among other things, on the type of study, the risk of bias and the body of studies as a whole. Missing evidence does not mean something is ineffective.
- Also called
- evidence-based, body of studies
“Evidence” means scientific proof. How robust it is depends, among other things, on the type of study, the risk of bias and the body of studies as a whole. In its recommendations, the 2021 S3 guideline distinguished “soll” (strong recommendation based on the evidence, grade A), “sollte” (grade B) and “kann” (open recommendation because of low evidence, grade 0). [1, Ch. C.1]
Important: if there is no evidence for a method, this does not mean it is ineffective, but that it has so far not been researched sufficiently. [1, Ch. C.1] The guideline expired on 23.03.2026. [2]
