Abstract

Currently, clinical practice must integrate evidence-based medicine. This requires a rigorous scientific method that includes identifying a knowledge uncertainty (the problem), formulating a question, conducting a systematic search of the available evidence, selecting the best valid evidence, interpreting and applying it, and if this evidence does not exist, the scientist (the physician) must generate that knowledge through a research design. A part of the methodological process is statistical analysis, which, for example, involves inputting clinical data (the study’s database) into a statistical machine that has various mathematical processing options (calculating statistical metrics) to obtain a result that must be validated, interpreted, and analyzed to justify its real-world applicability. This review aims to contextualize some basic statistical concepts and proposes a succinctly organized set of steps for conducting a statistical analysis, which is intended to encourage further exploration to develop a critical perspective when reviewing a research design.
