Kaplan-Meier survival curves of NSCLC patients. Kaplan-Meier survival curves for NSCLC patients based on the median level of fold change. The P-value was calculated using the log-rank test between patients with high- and low-fold changes. Disease-free or overall survival of patients with high vs. low miR-100 expression levels are shown. (A) The 5-year disease-free survival rate showed no difference between NSCLC patients with high miR-100 and those with low miR-100 (P = 0.078). (B) The 5-year overall survival rate of NSCLC patients with high miR-100 was significantly higher than that of those patients with low miR-100 (P = 0.006). P < 0.05 indicates a significant difference between groups. Corresponding P values analyzed by log-rank tests are indicated.
