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).
