Further, survival analysis showed that peripheral blood CCL28 (a CCR10 ligand) transcript levels were correlated (P < 0.05) with poor progression-free survival (Figure 1B) and Cox regression unadjusted or adjusted for sex, age, and physiological (SAP) score (Table 1) in the COMET IPF cohort (40, 41). The gene discussed is CCL28; the disease is idiopathic pulmonary fibrosis.
