SAUCEDO-MORENO, Eric M.  and  FENIG-RODRIGUEZ, José. Statistics in surgery, how to understand and apply basic concepts. Cir. cir. [online]. 2019, vol.87, n.6, pp.692-697.  Epub Nov 22, 2021. ISSN 2444-054X.  https://doi.org/10.24875/ciru.19000487.

It is estimated that a regular reader of biomedical publications will have access to 70% of journals with bivariate procedures with basic statistics, that is, any health professional with basic knowledge is capable of understanding the vast majority of published studies. That is why the need arises to write this text that aims to give an overview of the statistics applied to surgery, making reference to how and when to use each statistical procedure and of course how to interpret the results. We will handle definitions of concepts such as variables, hypotheses, confidence intervals, multivariate analysis, contrast of hypotheses, parametric and nonparametric methods and logistic regression. The importance of this guide is that all health professionals can interpret in a simple and concrete way the different statistical studies in their professional development.

Keywords : Statistics; Nonparametric methods; Parametric methods.
