Sequential analysis for the determination of prognostically significant LRGs in OC. A Illustration of differential expression analysis comparing OC tissues to normal controls, identifying genes with altered expression. B Venn diagram analysis to identify genes that overlap between the DEGs and LRGs. C Application of univariate Cox regression to identify LRGs with significant prognostic value. D Assessment of the distribution of LASSO coefficients. E Selection of the optimal penalty parameter in the LASSO model via cross-validation, ensuring model reliability. F Evaluation of the distribution of selected genes and their corresponding regression coefficients
