For the relationship between hub genes expression levels and the prognosis of NSCLC from Kaplan Meier Plotter, COL3A1, COL1A2, OGN, COL15A1, ASPN, and MXRA5 were associated with the overall survival of LUAD (Figure 8A), but the expression levels of these genes did not affect overall survival of LUSC patients. Here, COL3A1 is linked to non-small cell lung carcinoma.
