Abstract

[When it comes to categorical variables, it is necessary to distinguish whether a simply descriptive analysis is being carried out or a comparative analysis is being tried. Descriptive analysis does not present particular complexities, while comparative analysis must be centered on the objective of the research itself. In this chapter, we will mainly deal with how comparative analyses can be reported. This is with the aim to understand when and how a difference may or may not have clinical meaning, beyond the common and inadequate concept, of statistical significance.]
