STATISTICAL ANALYSIS
The data were analyzed using the SPSS (Statistical Package for the
Social Sciences) 18.0 software. The measured variables are presented
with mean ± standard deviation values, while the categorical variables
are presented with frequency and percentage values. Kolmogorov-Smirnov
or Shapiro-Wilk tests were used to assess the distribution of the data.
The numerical values that were compatible with normal distribution were
compared using t-test or one-way analysis of variance (ANOVA). Those
that did not show normal distribution were compared using Mann-Whitney U
test or Kruskal-Wallis test. Pearson’s chi-squared test was used to
analyze the categorical variables. p<0.05 was accepted as
statistically significant.
