From: Incidence and predictors of morphometric vertebral fractures in patients with ankylosing spondylitis
Comparisons of incidence of morphometric vertebral fractures (VFs). (A) The risk of VF was significantly increased in patients with previous VFs at baseline compared with those without. (B) The risk of occurrence of new VFs at 2Â years and 4Â years was higher in patients with an increase in C-reactive protein (CRP) levels at 2Â years post-baseline than in patients with a reduction.
