Six ferroptosis-related lncRNAs were selected to establish a prognostic signature. (A) Selection of the optimal turning parameters (log Ī») through the tenfold cross-validation. (B)The Lasso coefficient profile of 60 OS-related lncRNAs and imaginary perpendicular lines were drawn at the value chosen by tenfold cross-validation. (C) Multivariate Cox regression analysis showed 6 ferroptosis-related lncRNAs.
