VEGFA and spondylitis: When analyzing the relation between elevated VEGF levels (≥600 pg/mL) with radiographic spinal progression (modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS) ≥ 2 after 2 years) without genotype-stratification, we found a significant association in the total study population (OR: 3.11, 95% CI: 1.02–8.82) and—as has been described previously [15]—this association was extremely more pronounced in those patients presenting at baseline with syndesmophytes (n = 41) (OR: 34.7, 95% CI: 3.22–1594).
