The median IP-10 BALF concentrations in children with ATB, LTBI, asthma, ILD, lung anomalies, and RTI were 414 pg/mL (IQR 104–598 pg/mL), 191 pg/mL (IQR 157–371 pg/mL), 490 pg/mL (IQR 216–1486 pg/mL), 578 pg/mL (IQR 410.3–852 pg/mL), 571 pg/mL (IQR 90.7–1261.7 pg/mL), and 281.7 pg/mL (IQR 110.4–414 pg/mL), respectively (Figure 2A). The gene discussed is CXCL10; the disease is interstitial lung disease.
