Statistical analyses
Data are presented as mean (±) standard deviation and
as absolute variations (delta absolute), as indicated for each
analysis. After assessing the normality and homogeneity of
the data using the Shapiro-Wilk test and Levene’s test, respectively,
between- and within-groups comparisons were
performed using Split-Plot ANOVA (Mixed ANOVA) with
Scheffe’s post hoc test. When any of the dependent variables
did not show sphericity in the Mauchly’s test, the epsilon
of Greenhouse-Geisser was used to analyze the F statistic.
The level of significance was chosen as 5% (p≤0.05) and
all analyses were carried out using the Statistical Package
for the Social Sciences (SPSS) 15.0.
