IL-31 and IL-8 in Cutaneous T-Cell Lymphoma: Looking for Their Role in Itch

Figure 2

Correlations between IL-31 serum levels and LDH serum levels (a), B2MG serum levels (b), and itch VAS score (c). In this figure, 2 outliers were excluded for correlations involving sIL-31 (sIL-31 > 200 pg/mL), and the and R values presented refer to analysis excluding outliers. Statistical analysis was performed using Kendall’s tau-B correlation coefficient. Statistics (including/excluding the outliers): sIL-31 vs. LDH: ; R = 0.545/ ; R = 0.522; sIL-31 vs. B2M: ; R = 0.406/ ; R = 0.383; sIL-31 vs. SC count: ; R = 0.406/ ; R  =  0.423; and sIL-31 vs. pruritus VAS score: ; R = 0.530/ ; R = 0.561. B2M, beta 2 microglobulin; CTCL, cutaneous T-cell lymphoma; IL, interleukin; LDH, lactate dehydrogenase; SC, Sézary cells; and sIL-31, interleukin-31 serum levels.
