Statistical Analysis
SPSS version 11.5 statistical program was used in the analysis of the data. For descriptive analyses; the quantitative variables were summarized as mean ± standard deviation and median (minimum-maximum), while the qualitative variables were summarized in percentiles. In order to test whether categorical differences were present in the quantitative variables with more than two categories; the one-way ANOVA test was used when the normal distribution presumptions were met, whereas the Kruskal-Wallis H test was used when the normal distribution assumptions were not met. Differences between two dependent quantitative variables were analyzed with the paired t-test when normal distribution assumptions were provided or with the Wilcoxon signed-rank test when normal distribution assumptions were not provided. The statistical significance level was accepted as 0.05.
