Fig. 1. Serum DKK1 levels were higher in ankylosing spondylitis (AS) patents than those of control patients after adjusting for age. The human DKK1 levels were measured in the collected sera (healthy control [HC], n=30; AS, n=103) using ELISA. Since the classic DKK1 standard curve ranges 0∼2,000 pg/mL, we fixed the values as 2,000 pg/mL if the DKK1 levels go over 2,000 pg/mL. The bars show means±standard error of the mean; *p<0.05.
