“…The criterion of testing under double-blind conditions is also usually not viewed in a discriminatory way (see below), which has severe consequences. A particularly contentious point is whether the results of important, methodologically outstanding single studies have priority over the results of meta-analyses of all studies related to a specific issue [6,23,80]. Most guidelines prefer results from meta-analyses alone or together with results from single studies.…”

“…The treatment guidelines of the World Federation of Biological Psychiatry [5,6,8,9,11,30,31,[38][39][40][41] relate to a different system of grading evidence. The crucial difference from the evidence criteria of many other guidelines is that the highest level of evidence is not based on the results of meta-analyses but on the results of important and methodologically outstanding and adequate single studies [79].…”

“…Quite often in psychotherapy research instead of randomised parallel group conditions, the waiting group approach was used as a surrogate of the parallel group design, which probably increased effect sizes in a significant way [6]. This argumentation was based on single studies and the related evidence grading but of course it is similar for the methodological evidence grading.…”

Given the importance of the term 'evidence' in evidence-based medicine (EBM), the meaning of this term is evaluated, going back to the philosophical tradition and current meaning of the terms 'evidence' and 'truth'. Based on this, current problems in the definition of evidence and in the grading of evidence in EBM are described, taking examples from the field of psychiatry and especially pharmacopsychiatry. These problems underline that the use of the term evidence in EBM is inconsistent and inconclusive. This should be fairly stated in all EBM-related publications, especially in EBM-based guidelines, to avoid severe misunderstandings in and outside the field of psychiatry. Although EBM might have increased empirically driven rational decision-making in psychiatry/medicine, the current limitations should be carefully considered.
