Differential expression by patient race identified 173 genes meeting Benjamini–Hochberg (BH)-adjusted P value significance (DEGs) (Supplemental Table S3), with pathway enrichment identifying “lung fibrosis” (P = 0.002), “adipokine signaling” (P = 0.003), and “TNF-related induction of apoptosis” (P = 0.006) as the three most-enriched pathways (Supplemental Table S4). Here, TNF is linked to pulmonary fibrosis.
