  1. *The description of Set I and Set II are given in the experimental methods section.
  2. **Fold change (FC) represents the ratio of means of 10 (Set I) or 5 (Set II) skin samples per group. Data are based on normalized XIC ratios, as described in the experimental methods section. PsA, psoriatic arthritis; PsC, cutaneous psoriasis.
  3. ***P-Values were calculated using the non-parametric Mann-Whitney U test.
