Data analysis
The statistical analysis of the data was carried out by the author Dr. Idiberto José Zotarelli Filho, MSc, Ph.D., and interpreted by the other co-authors. For data analysis, a database was built on a Microsoft Excel spreadsheet that was exported to the Minitab 18® statistical program (version 18, Minitab, LLC, State College, Pennsylvania, USA) (Minitab®) [16]. Common descriptive statistical analysis was performed, obtaining the values ​​of total N, mean, standard deviation, confidence interval (CI), and percentage (frequency) for the variables involved. The Variance (α2) and One-Way (ANOVA) test were applied, adopting the α level less than 0.05 with a statistically significant difference for the 95% CI. The value of R-sq (R2) was analyzed to discover the imprecision or heterogeneity of the analyzes, adopting the codes of low association ≤25%, medium association 25% <X <50%, and high association≥50%.
