Identification of FR-related lncRNAs in HCC patients and construction of the ferroptosis-related lncRNA prognostic signature. (A) Sankey relational diagram for 269 ferroptosis genes and 496 FR-related lncRNAs. (B) Volcano plot of the differentially expressed FR-lncRNAs (C) LASSO coefficient profiles of 115 FR-lncRNAs. (D) To construct a prognostic signature, 11 best candidate FR-lncRNAs were obtained. (E) Forest map showed 6 lncRNAs identified by multivariate Cox regression in the training group.
