From: Association of cytokine and matrix metalloproteinase profiles with disease activity and function in ankylosing spondylitis

  Response variable (CRP)a
Independent variable Regression coefficient (SE) Pvalue
MMP-3 (pg/ml) 1.108 × 10-5 (2.335 × 10-6) 0.000005
MMP-8 (pg/ml) 4.189 × 10-6 (1.610 × 10-6) 0.010
MMP-2 (pg/ml) -2.277 × 10-6 (9.477 × 10-7) 0.018
  1. SE, standard error. aC-reactive protein (CRP) levels were log transformed to normality before analysis.
