In addition, survival analysis by KM plotter (http://kmplot.com/) (accessed on 04 March 2022) shows that the low expression levels of C6orf223, SNAI3-AS1, NEURL3, IGFL2-AS1, and LINC02243 are associated with short survival in NSCLC patients, and that high expression levels of LINC02643 are related to poor prognosis in NSCLC patients (Figure 9C). This evidence concerns the gene IGFL2 and non-small cell lung carcinoma.
