Firstly, an exploratory analysis of the data was performed. Continuous variables
with normal distribution are reported as mean + standard deviation and
categorical variables are presented as absolute numbers and percentages. The
Fisher exact test was used to compare categorical variables, the McNamer's test
was used to evaluate the effect of the intervention and ANCOVA was proposed to
compare the groups and to verify the effect of the covariates.22 This analysis assumes that its
residues have a normal distribution with mean 0 and variance s2 (link) constant. Transforms were used
in response variables that did not reach the assumption. Differences were
considered to be statistically significant when p < 0.05. The SAS system
(version 9; SAS Institute, Cary, NC) was used for all statistical
calculations.
