TNFRSF9 and idiopathic pulmonary fibrosis: The univariable associations of the ILA score [IPF transcripts] with ILA in both cohorts is shown in Fig. 2A. In multivariable models (Table 2), the ILA score [IPF transcripts] was associated with ILA in the COPDGene testing set and ECLIPSE (meta-analysis OR 1.4 [95% CI: 1.2–1.6], p = 6.8e-5).
