The median IP-10 plasma levels in children with ATB, LTBI, asthma, ILD, lung anomalies, and RTI were 82 pg/mL (IQR 50–113 pg/mL), 152 pg/mL (IQR 129–253 pg/mL), 131 pg/mL (IQR 101–331 pg/mL), 186 pg/mL (IQR 126.0–206 pg/mL), 127.8 pg/mL (IQR 84.1–258.1 pg/mL), and 115.1 pg/mL (IQR 72.5–165 pg/mL), respectively (Figure 2B). This evidence concerns the gene CXCL10 and interstitial lung disease.
