Unsupervised clustering analysis performance. A Representative H&E staining images depicting healthy control, LPS-induced IPF, and lung cancer groups in a mouse model. B PCA plots with 95% confidence ellipses showing targeted chemical profiling differences between lung cancer and IPF in all chemicals (untargted profiling including phenol, toluene, etc.), all SCA (C10-14), even (C10, 12, 14), and odd (C11, 13) SCA
