Aspectos metodológicos na construção de projetos de pesquisa em Nutrição Clínica

Abstract

This text aims to foster the reflection and criticism in the process of developing research projects in clinical nutrition. We present aspects regarding the evidence, validity, and reliability of results of studies in this field. Appropriate study planning is critical, from defining the design and type of experiment, going through the ethical aspects, population choice, and calculation of sample size, to the assessment of the feasibility of the risks involved in study execution. Once the information is collected, the next stages correspond to the description of the results, statistical analyses, verification of the consistency of these results, and ultimately their correct interpretation.
