Values are presented as mean ± standard deviation for parametric variables and median (25th-75th CI) for non-parametric continuous variables. For categorical variables, values are presented as percentages
^aObtained from chi-square test for categorical variables
^bObtained from independent-samples T-test for parametric continuous variables
^cObtained from Mann–Whitney for non-parametric continuous variables
Bold values represent the significant values
