Construction of NSCLC immune subgroups by NMF classification. A NMF of the NSCLC cohort using the LM22 signature gene provided by CIBERSORT revealed better categorization when rank = 2 or 3; B Determination of k value using the NMF rank survey with multiple parameters; C Principal component analysis (PCA) using the first two PCs, PC1 and PC2, indicated that most NSCLC samples were PC1 < 0, which was then divided into two major groups by PC2. NMF subgroups and different pathological groups could be separated by PC2. Percentages in parentheses represented percent variance explained; D Monocle analysis constructed a pseudo timeline of immune characteristic genes, showing divergent immune composition of each NMF subgroup
