Quantitative variables are expressed in quartiles (non-parametric) or some in mean and standard deviation (parametric). The qualitative variables are expressed in frequency and percentage. Non-parametric tests were used for the qualitative variables. It was verified whether the quantitative data are normally distributed by means of the Kolmogorov-Smirnov (n> 50) or Shapiro-Wilk (n≤50) test, which allowed the use of parametric or non-parametric tests (Table 13) .
