Table 1 shows the demographic features of the population
included in this study according to group allocation. Only the
initial pain intensity differed significantly between any of the
groups (only between groups 1 and 3) (P = 0.0086), at a significance
level of 5%.
Independent of group allocation, comparison of patient
characteristics between individuals who finished the treatment
protocol (n = 137) and those who did not (n = 13) using one-way
Anova and the Kruskal-Wallis test showed that there was no statistically
significant difference between these groups (Table 2).
