From: An eight-miRNA signature as a potential biomarker for predicting survival in lung adenocarcinoma
Kaplan–Meier and ROC curves for the 8-miRNA signature in TCGA non-smoking LUAD cohort. (A) The Kaplan–Meier curves for LUAD risk groups obtained from the TCGA non-smoking LUAD cohort (n = 145) divided by the median cutoff point. Non-smoking patients with high scores had poor outcome in terms of OS (Median OS: 46.0 months vs. 59.3months, P = 0.027). (B) The ROC curve had an AUC of 0.686 (P = 0.023). The permutation P value was obtained from 1,000 permutations for testing the null hypothesis (AUC = 0.5).
