Multivariate Cox regression analysis of the three individual ir-lncRNAs (Table 1) showed that out of the three lncRNAs, RP11-291B21.2 was most often associated with survival (STAD, GBM, KIRP, KIRC), followed by AC092580.4 (BRCA, STAD, LGG) and PCED1B-AS1 (LUAD, KIRP). The gene discussed is PCED1B; the disease is glioblastoma.
