^ap-Values represent statistically significant differences between the low and high CTQ groups with post-hoc test using LSD.

^bThe participants were divided into 3 subgroups based on the 25% and 75% quartiles of the total CTQ score (= 34.0 and 48.5, respectively): the low CTQ group (lower 25%), the middle CTQ group (25–75%), and the high CTQ group (upper 25%).
