From: Chondrocyte activity is increased in psoriatic arthritis and axial spondyloarthritis
a Pro-C2 was significantly increased in the axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA) groups compared with the healthy control group. b C-Col 10 concentrations were slightly but significantly higher in the PsA group compared with the healthy control group. Error bars are shown as SEM. One-way analysis of variance was performed for intergroup comparisons. *p < 0.05, ****p < 0.0001
