a
Indicates comparisons using independent sample t-tests and is expressed as mean ± standard deviation.
b
Indicates comparisons between groups based on Mann–Whitney U test and is expressed as median, interquartile range, and 95% CI.
*
Indicates significant differences between groups. One person in the control group had missing ICA data.
