S100A7 and systemic sclerosis: Upon evaluating the levels of inflammatory biomarkers depending on the subtype of SSc, the analysis showed no significant differences in calprotectin and psoriasin levels between diffuse and limited forms of SSc (0.58 ng/mL (−1.42 to 0.31), p = 0.174 [n1 = 28, n2 = 21], and 0.26 ng/mL (−0.83 to 1.15), p = 0.95 [n1 = 8, n2 = 6], respectively (Supplementary Material Table S3).
