Statistical Analysis
Whether the data fits the normal distribution was investigated with the D’Agostino Pearson test. The data that did not fit normal distribution were presented as medians. While the Mann Whitney U-test was used to compare two groups that did not fit normal distribution, the Kruskal-Wallis test was applied for more than two groups. Correlation analysis was performed with the Spearman correlation test. For the two-tailed p-value, < 0.05 was accepted as significant. Statistical calculations were conducted using the Medical program (Medcalver 16, Ostend, Belgium).
