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.
