a BAFF level was also associated with the grade of X-ray. b X-ray of hands9 of RA between low BAFF level and high BAFF level. Solid arrows show joint space stenosis, and dotted arrows show joint subluxation. c The association of X-ray with RF level. d The association of X-ray grade with anti-CCP antibody level. e The association of X-ray grade with CRP level. P values < 0.05 were considered significant. r, correlation coefficient; P, significant level.
