Evidence-Based and Personalized Medicine.  It's [AND] not [OR]. 
Good clinical practice is an amalgamation of personalized medicine with evidence-based medicine in the best interests of patient.  Hence, our title uses Boolean operators to indicate that it is [AND] not [OR].  This is the syntax of formal searching for systematic reviews, ensuring that all the evidence is found.  Comprehensive evidence-based guidance can thus be formulated.  Many residents and fellows around the world, and their chiefs, are now exposed to consensus documents, white papers, levels of appropriateness, and guidelines and are in many jurisdictions expected to comply with them.  However, they are the summation of many forms of evidence, each of which has its place, and we consider them in turn in this article.
