Data analysis
SPSS 22.0 Windows program was used to analyze the data. One Sample
Kolmogorov – Simirnov and the Shapiro-Wilks tests were used to examine
whether the differences between the groups and differences between the
groups by gender were normally distributed, and it was found that the
data did not show a normal distribution. Therefore, non-parametric
analyses were used. Mann–Whitney U-test was used in the comparison of
parameters between the groups and (p <0.05) was considered
statistically significant. G*Power 3.1.9.7 program was used to calculate
the sample size. One hundred ten sample size results were obtained for
each group, in this calculation (test=t-test (Wilcoxon-Mann-Whitney test
(two groups)), Analysis: A priori: Compute required sample size, Tail(s)
=Two, Parent distribution=Normal, Effect size d=0.5, α err prob=0.05,
Power (1-β err prob)=0.95, Allocation ratio N2/N1=1).
