*Differences in continuous variables were tested using Wilcoxon Rank Sum tests for non-normally distributed variables and the Student t-test for normally distributed variables; differences in categorical variables were tested using χ2 tests; p-values < 0.05 were considered significant
aPercentages represent column percentages
Q1 Lower 25th percentile, Q3 Upper 25th percentile, SD Standard deviation
