I found this image by searching evidence-based medicine on Google Images.
I chose this image because I think it demonstrates the best of the images that I found what ebm is about and allows for easy understanding of the ebm concept. This image comes from Florida State University's webpage tutorial on evidence-based medicine (ebm).
According to Sackett et al., ebm is a systemic approach to solving clinical problems that integrates patient values and expectations with individual clinical expertise and the best research-based evidence available. (Sackett DL, Strauss SE, Richardson WS, et al.(2002). Evidence-based medicine: how to practice and teach EBM. London: Churchill-Livingstone).
