AGUERO MARTINEZ, María Oslaida. Systematic reviews and meta-analysis in clinical practice: an approach to the topic. Rev cuba anestesiol reanim [online]. 2013, vol.12, n.3, pp. 244-251. ISSN 1726-6718.

Introduction: there is a current named "evidence-based medicine" and it brings a kind of novel conceptual framework or paradigm for solving clinical problems. This way of practicing medicine aims to bring more results from the clinical research to the medical practice. It is required then solutions to face the present excess of information from the clinical research. Objective: to carry out an approach to systemic reviews and meta-analysis as an efficient method to summarize the best available scientific evidence. Development: both terms are not necessarily equivalent though they are closely related. Meta-analysis is a quantitative synthesis of information that should be based on a literature systemic review to eliminate possible selection biases. A systemic review may or may not be accompanied of a meta-analysis. Conclusions: the systemic reviews with meta-analysis provide more precise estimates of the effects of health care than those derived from the individual studies and, therefore, they constitute a methodological tool for evaluating the effect of a risk factor or the effectiveness of a therapeutic measure. This allows us to broaden the scientific knowledge departing from truly reliable elements, in order to give our patients the best and safest service.
