Table 2 Influencing factors on CXCL1 by multiple linear stepwise regression analysis

From: Chemokine CXCL1 as a potential marker of disease activity in systemic lupus erythematosus

Confounding factor Lg CXCL1
β Coefficient (95% CI) p value Adjust R2
Positive IgG ANA 2.371 (1.734–3.009) < 0.001  
Positive HA ANA IgG 1.231 (0.525–1.937) 0.001 0.604
Lg anti-dsDNA 0.409 (0.062–0.755) 0.021  
  1. HA ANA IgG, high-avidity IgG ANAs; Lg CXCL1/anti-dsDNA represent the logarithmic level of CXCL1 and anti-dsDNA
