The nomogram model with EXO1 shows a superior diagnostic and prognostic performance in LUAD. (A) Diagnostic ROC curves to distinguish LUAD tissues and normal tissues based on the EXO1 expression levels. (B) Time-dependent survival ROC curves to predict 1-, 3-, and 5-year survival rates of LUAD patients based on the EXO1 expression levels. (C) ROC curve analysis to evaluate the prediction efficacy of the nomogram model that includes EXO1 expression levels and clinicopathological factors (clinical stages, TNM stages, tumor status, age, and smoke) to predict the 1-, 3-, and 5-year survival rates of LUAD patients.
