Abstract

The evidence based medicine offers us very useful tools to solve clinical problems by means of the efficient analysis of scientific literature. If we acquire and exercise these methodological tools, we will be able to value any scientific evidence and integrate it with our knowledge and clinical experience, and also we will be able to decide on its applicability and suitability in a concrete patient. In this article we will review the general principles of the critical appraisal of scientific literature. Also we will review the main criteria to consider in the analysis of the validity and applicability of the studies of evaluation of health interventions and diagnostic tests.
