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). Here, CCR10 is linked to idiopathic pulmonary fibrosis.
