In order to analyze the relationship between the variables of spirometry (FEV1, FVC, FEV1 / FVC) and the number of Step Test the steps that we used the Spearman correlation test, adopting a level of significance of 5%. When comparing types and times of NIV use between study groups, there was no statistically significant difference in the number of steps in Step Test.
