Fig. 5. Dynamic changes in CXCL10 levels after 0, 3, 6, 9, and 12 months of treatment. ANOVA test was applied. In patients who had non-segmental vitiligo (NSV) without alopecia areata (AA) or autoimmune thyroid disease (AITD) (A), the level of CXCL10 initially decreased significantly after 3 months treatment, then continuously decreased in month 6, 9, 12. In patients who had NSV with AA (B) and those who had NSV with AITD (C), the level of CXCL10 initially decreased significantly after 6 months of treatment, then continuously decreased in month 9, 12. In patients who had NSV with both AA and AITD (D), the level of CXCL10 initially decreased significantly after 9 months of treatment, then continuously decreased in month 12. NS: no significance. ^**p<0.01, ^***p<0.001, ^****p<0.0001.
