Both total BLs and PLI score were found to correlate negatively with healthy lung volume (respectively, τ −0.36, P < 0.014 and τ −0.5, P < 0.0001) and positively with total ILD volumes (τ 0.43, P < 0.0001 and τ 0.58, P < 0.0001), GGO (τ 0.35, P < 0.017 and τ 0.45, P < 0.0001), RET (τ 0.44, P < 0.0001 and τ 0.56, P < 0.0001) and total fibrosis (τ 0.44, P < 0.0001 and τ 0.51, P < 0.0001). This evidence concerns the gene RET and interstitial lung disease.
