How Case Reports were Defended against Evidence-Based Medicine, The New Empire?

چکیده
For a few years and since the release of the expression on Medline in 1992 by Gordon Guyatt et al., interest in the Evidence Based Medicine (EBM) had skyrocketed and had induced a kind of globalization of its teaching. Undoubtedly, we live in the era of EBM in which scientific knowledge and research works are classified in a pyramid hierarchy according to their levels of evidence. At the top of this pyramid, level 1, we find randomized clinical trials, meta-analyzes, systematic reviews, and secondarily added teleoanalysis [1,2]. These studies are expected to have the highest level of evidence. At the bottom of the pyramid, level 4, we find the case reports and case series with a level of evidence obviously lower.
