3.2.1. HIT-6.
The HIT-6 are presented in Table HIT-6 of the 2 groups of patients before and after treatment.Table 3 presents the mean and standard deviation of the total score for the HIT-6 for every group at each time point. There was no difference in HIT-6 between the 2 groups at baseline. Compare with the CLST, the HIT-6 of the groups were significantly decreased after the CST at the week 4 (group A) and week 8 (group B). While the change was not obvious after CLST in group A at week 8 and group B at week 4 compared with prior to treatment.This figure visually shows the change trend of HIT-6 with over time. The score of group A decreased significant from baseline to week 4 and group B decreased obvious from week 4 to week 8.
