Correlation of PDGFB with clinical indices. A Correlation between PDGFB and BASFI. B Correlation between PDGFB and all clinical information. C Correlation between PDGFB and ΔmSASSS in Chinese AS patients in validation II-40. D Expression level of PDGFB secreted from monocytes after stimulation with M-CSF and RANKL for 7 days, which were analyzed by ELISA. E TRAP staining of the osteoclastogenesis assay for 7 days stimulation. The expression levels of PDGFB in the AS group and control group were compared by unpaired sample t-tests. * P < 0.05
