A total of 92 subjects had No or High ideation group assignment.
#
non-parametric tests: Fisher’s exact for count, Kruskal-Wallis test for three group comparison with post-hoc Wilcoxon rank sum test using Bonferroni correction, and Wilcoxon rank sum test for two group comparison.

Low-SI subjects were excluded for SI group comparison.
