  • P values for difference between PsA and matched controls analysed with mixed linear and logistic analysis.

  • Unless stated, continuous values are mean (SD), categorical values are number (%).

  • *Comparing patients with PsA and matched controls.

  • †Comparing patients with PsA and all non-matched controls.

  • HDL, high-density lipoprotein; HUNT, Nord-Trøndelag Health Study; LDL, low-density lipoprotein; PsA, psoriatic arthritis.
