  • The analysis included the entire study population. For patients with PsC, active and damaged joint counts were recorded as zero.

  • Spearman correlation was used for pairs that included hsCRP otherwise Pearson correlation was used.

  • BMI, body mass index; HDL, high-density lipoprotein; HOMA, homeostasis model assessment; hsCRP, high sensitivity C-reactive protein; LDL, low-density lipoprotein; PASI, psoriasis area and severity index.
