Statistical analysis
Statistical analysis of the research data was performed with the statistics package IBM SPSS 22.0 (IBM, Armonk, NY, USA). Numerical data was examined by the Shapiro-Wilk test as to whether it showed normal distribution. Distributions of descriptive information on patients obtained as a result of the study were given as means and SDs. Since the data was found to be normally distributed, the non-parametric Wilcoxon signed rank test was used in dependent groups, and the Mann-Whitney U test and Kruskal Wallis-H test were used for two independent variables. The level of statistical significance was determined as p < 0.05.
