Lung P16 gene expression levels in participants affected by idiopathic pulmonary fibrosis (IPF, n = 74) and controls (n = 73) captured through microarray analysis and expressed as means ± SD (A); Unadjusted Spearman’s rank correlations plots between lung P16 gene expression and circulating levels of activin A (B), GDF15 (C), and MMP7 (D); Biomarkers selected by the LASSO regression analysis to predict lung P16 gene expression (E).***p < 0.001
