Fig. 1From: Biomarkers of interstitial lung disease associated with primary Sjögren's syndromeRelationship between serum levels of cytokines and the severity of ILD (ILA score 0 vs. ILA score 2 + 3) by HRCT in pSS. Panels a–c demonstrate the relationship between the natural log of serum a) KL-6, b eotaxin/CCL11, and c TNFα levels and ILD severity (p = 0.0002, 0006, and 0.0182, respectively). Each symbol represents an individual patient; horizontal lines show the mean value (natural log) of serum levels for specified cytokines. P values were determined by Mann–Whitney U testBack to article page
