Fig. 4. The mRNA expression of CXCR3 in circulation. ANOVA test was applied. The mRNA expression of CXCR3 was significantly higher in patients with NSV than in healthy controls (HCs). In addition, it was higher in patients who had nonsegmental vitiligo (NSV) with either alopecia areata (AA) or autoimmune thyroid disease (AITD), and in those who had NSV with both AA and AITD than in patients who had NSV without AA or AITD. There was no significant difference in CXCR3 mRNA expression between patients who had NSV with AA and those who had NSV with AITD. NS: no significance. ^*p<0.05, ^**p<0.01, ^***p<0.001.
