Abstract
It may come as a surprise to both clinical practitioners and medical students if evidence-based medicine is linked to epidemiology, a remote field of clinical medicine. Yet it is not an end in itself.
The aim is not to discourage the reader, but to emphasize one of the pillars on which the evidence-based medicine movement is based, as well as the fact that there is quantitative evidence at the heart of this movement. The main ambition of the publication is to explain the way in which quantitative evidence is generated, the current technical possibilities of its search, and especially its assessment in terms of validity, biological and clinical relevance, respectively. applicability, to a particular patient.
Although the quantitative side of the evidence is emphasized, the mathematical apparatus used has been minimized to an absolute minimum and the text is written to be understandable both for beginners (an explanatory dictionary is attached) and to provide interesting information for clinical professionals who on the evidence they have already encountered.
