Note. a %s are column percentages except the first row. The sum of %s of a variable may not be 100 due to missing values
b P-values are determined using Fisher’s exact tests for categorical and Kruskal Wallis tests for continuous variables. P < 0.05 are in bold character. NAs are due to limited sample size. P < 0.05 are in bold character
