Risk model for BC patients based on ferroptosis-related lncRNAs. (a) Univariate Cox regression analysis showed that the included ferroptosis-related lncRNAs were significantly associated with clinical survival prognosis. (b) The tuning parameters (log l) of OS-related proteins were selected to cross-verify the error curve. According to the minimal criterion and 1-se criterion, perpendicular imaginary lines were drawn at the optimal value. (c) The LASSO coefficient profile of 13 OS-related lncRNAs and perpendicular imaginary line were drawn at the value chosen by 10-fold cross-validation. (d) Ten ferroptosis-related lncRNAs with independent prognosis and survival correlation were shown by multivariate Cox regression analysis. (e) Sankey relational diagram for the ferroptosis-related genes and the lncRNAs used to construct the risk model.
