CXCL10 and systemic sclerosis: As can be seen in Fig. 7a, cxcl10 relative gene expression was higher in fibroblasts treated with BAL obtained from patients with SSc-ILD [Median (IQR): 1.5 × 10−5 (1.1 × 10−5 to 2.4 × 10−5)] compared to BAL from SSc without ILD patients [2.6 × 10−6 (1.4 × 10−6 to 4.8 × 10−6)], P = 0.004, 95% CI: 5.2 × 10−6 to 2.1 × 10−5.
