Kaplan–Meier estimation of relapse-free survival of early-stage lung adenocarcinoma patients. Mutations in the D-loop region (a) were associated with longer relapse-free survival, whereas mutations in Complex IV genes (c), Complex V genes (d), and Complex IV and Complex V combined (e) were associated with shorter relapse-free survival. No significant association was observed for Complex I mutations (b). For the risk-score-based stratification, patients with low risk scores showed better relapse-free survival (f). p-values were computed using the two-sided log-rank test.
