From: Blood chemokine profile in untreated early rheumatoid arthritis: CXCL10 as a disease activity marker
Association of CXCL10 with other chemokines in untreated early rheumatoid arthritis patients. a Orthogonal projection to latent structures (OPLS) column loading plot depicting the association between the levels of CXCL10 (y variables) and other chemokines (x variables) in patients with ueRA (n = 43). x variables represented by bars pointing in the same direction as CXCL10 are positively associated, whereas variables with bars pointing in the opposite direction are inversely related to CXCL10. b Correlation analyses between the levels of CXCL10 and other chemokines in ueRA patients (Spearman rank correlation test; r). *P ≤ 0.05, *** P ≤ 0.001, **** P ≤ 0.0001
