Normally distributed variables with even variance were presented as mean ± SD, skewed variables as median (lower quartile to upper quartile), and categorical variables as n (%). Continuous variables were compared using Student’s t-test or Mann–Whitney U test depending on distribution. Pearson’s χ2 tests were used to compare categorical values
