Estimation of the accuracy of the ferroptosis-related lncRNAs prognostic signature in LUSC patients. Univariate Cox regression analysis showed the correlation between OS and various clinicopathological parameters such as age, gender, and stage, and ferroptosis-related lncRNAs prognostic signature risk score. The remaining parameters (P<0.05) were associated with OS in addition to gender, where the risk score was statistically significant (P<0.001). Multifactor Cox regression analysis showed age, stage, and risk score were prognostic indicators for OS rates of LUSC patients, in which the risk score was statistically significant (P<0.001). lncRNA, long non-coding RNA; LUSC, lung squamous cell carcinoma; OS, overall survival.
