Figure 4

(A) Comparison of sTNF-α levels (pg/ml) in 236 controls, 214 vitiligo patients, 158 generalized vitiligo patients and 56 localized vitiligo patients, as determined by ELISA. (B). Comparison of sTNF-α levels (pg/ml) with respect to TNF-α promoter haplotypes in 214 vitiligo patients and 236 controls, as determined by ELISA. (C) Comparison of sTNF-α levels (pg/ml) with respect to activity of the disease in 150 patients with active vitiligo and 64 patients with stable vitiligo, as determined by ELISA. (D) Comparison of sTNF-α levels (pg/ml) with respect to gender differences in 97 male patients and 117 female patients with vitiligo, as determined by ELISA.
