Figure 5From: Change in serum KL-6 level from baseline is useful for predicting life-threatening EGFR-TKIs induced interstitial lung diseaseThe ratios of the serum levels of KL-6 at the onset of EGFR-TKI related ILD to those at baseline on the basis of the sub-classifications of EGFR-TKIs induced ILD. Open, shaded, and solid bars represent hypersensitivity pneumonitis (HP) pattern, cryptogenic organizing pneumonia/eosinophilic pneumonia (COP/EP) pattern, and acute interstitial pneumonia (AIP) pattern, respectively. There is a significant difference in these ratios between AIP pattern and the other patterns (p = 0.005).Back to article page
