Table 5 Multiple regression analysis showing baseline association of PC3 (MMP-8, MMP-9, HGF, CXCL8) with the BASDAI

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

  Response variable (BASDAI)a
Independent variable Regression coefficient (SE) Pvalue
Female 0.282 (0.128) 0.029
PC3 0.080 (0.027) 0.004
  1. HGF, hepatocyte growth factor; MMP, matrix metalloproteinase; PC, principal component; SE, standard error. aSquare root transformation of the Bath ankylosing spondylitis disease activity index (BASDAI) was carried out to achieve a normal distribution.
