STATISTICAL ANALYSIS
For data analysis, a database will be built in a Microsoft Excel
spreadsheet which will be exported to the statistical program Minitab
18®. Common descriptive statistical analysis and the Anderson-Darling
normality test will be performed for all non-dichotomous numerical
variables, such as BMI, age, and gender. According to the results of the
Normality Test, the Kruskal-Wallis non-parametric test will be applied,
adopting α level < 0.05 with statistically significant
difference (95% CI), or the Chi-square parametric test, adopting α
level>0.05 with statistically significant difference (95%
CI). Due to the presence of age and gender continuous predictors, linear
regression analysis will be applied, adopting α level <0.05
with significant influence (95% CI).
