Figure 6. Correlation analysis of patients' overall survival and disease-free survival vs. expression of miR-21, miR-155, and miR-21/155 in NSCLC.

(A–C) The overall survival rates of patients with different levels of miR-21 (A), miR-155 (B), and miR-21/155 (C) in NSCLC. (D–F) The disease-free survival rates of patients with different levels of miR-21 (D), miR-155 (E), and miR-21/155 (F) in NSCLC.
