  1. Data conforming to a normal distribution are presented as mean ± standard deviation, while data with a non-normal distribution are presented as median (interquartile range). For normally distributed continuous data, differences between two groups were analyzed using Student’s t-test. As for non-normally distributed data between two groups, the Wilcoxon test was employed for the comparison. The P-values were corrected using the Bonferroni method.
