Figure 6: Spearman’s correlation was performed and clearly demonstrated an almost linear positive association between Egfr mRNA levels and protein levels in patients with different IIPs (a), between Egfr and COL1A2 mRNA in patients with different IIPs and finally a negative correlation between Egfr mRNA levels and functional parameters of disease severity and prognosis including forced vital capacity (FVC) (c) and diffusion lung capacity for carbon monoxide (DLCO) (d) in patients with IPF.
