To investigate the relation between FAP, COLI (COL1A1, COL1A2), and FN1 expression in GBM, we divided 357 primary IDH‐wild type GBMs into terciles according to the expression of FAP and included the upper (HighFAP, n = 119) and the lower (LowFAP, n = 119) terciles in the following analyses. The gene discussed is COL1A2; the disease is glioblastoma.
