Statistical analysis was performed using Statistical Package for Social Sciences software (SPSSV21, Chicago, IL). Data normality was tested by the Kolmogorov-Smirnov test. To perform the variables comparison, the Mann-Whitney test was performed. To verify the correlation between the variables, the Spearman correlation test was used. Values of p<0.05 were considered significant. The intensity of the relationship of the correlation coefficient values were interpreted according to the following guidelines: 0 = zero; 0.10-0.39 = weak; 0.40-0.69 = moderate; 0.70-0.99 = strong, 1 = perfect, regardless of whether positive or negative.
