Covariates in both regression analyses were serum HGF, MMP-3, VEGF, and the following variables known to be associated with bone metabolism: age, sex, BMI, CRP, and smoking. Empty spaces signify that the covariate was excluded in the stepwise linear regression analysis
HGF, hepatocyte growth factor; MMP-3, matrix metalloproteinase 3; VEGF, vascular endothelial growth factor, BMI, body mass index; CRP, c-reactive protein; mSASSS, modified stoke ankylosing spondylitis spinal score; BMD femoral neck, bone mineral density femoral neck
