Statistical Analysis
Data were analysed using the IBM SPSS V22 software. Normality of
distribution was tested using the Kolmogorov-Smirnov test. A
Kruskal-Wallis test and Man-Whitney U was used to compare the
non-normally distributed data. The relationship between variables was
examined using a Spearman’s correlation analysis. Non-normally
distributed data were presented as median (minimum–maximum). The
significance level was accepted as p < 0.05.
