Estructuras metodológicas PICO y PRISMA 2020 en la elaboración de artículos de revisión sistemática: Lo que todo investigador debe conocer y dominar

Writing a scientific article for a systematic review of the scientific literature implies that the researcher, who may be a novice student or an outstanding professional, has developed certain skills and abilities in search, methodology, writing, presentation of results and follows a series of clear guidelines that provide the structure and ensure that the research can be replicated, which takes time to develop. In this context, the general objective of this research was to delve into the PICO (Population, Intervention, Comparison, Outcome) and PRISMA (Main elements for developing systematic reviews and meta-analysis) methodological structures for the development of a correct research question and search for scientific articles for the systematic review, serving as a guide by presenting theory and examples of its applicability. The methodology was a review of the scientific literature under the PRISMA methodology for the Scopus database, complemented with Scielo, obtaining a total of 15 articles for analysis. The results were able to go into depth and provide examples of the application of the PICO methodologies, related to the development of the research question, and PRISMA related to the systematic search for scientific articles. The limitations of the research were related to the different ways, some correct and others with deficiencies, in which the researchers use and apply both methodologies, making the preparation of this manuscript essential.
