Fig. 2

A prognostic signature containing six cuproptosis-related lncRNAs was constructed for LUAD patients. A The Sankey diagram shows the correlation between the expression of 13 cuproptosis-related genes and various lncRNAs in LUAD patients. B, C LASSO coefficient values and vertical dashed lines were calculated at the best log (lambda) value. D The forest map shows the relationship between 38 cuproptosis-related lncRNAs and prognosis by using univariate Cox regression analysis. Red indicates a positive correlation, while green indicates the opposite
