Figure 5.
Kaplan–Meier curves for overall survival of NSCLC assessed using the log-rank test. (A) High expression of miR-4634 in lung SCC, ADC, and non-CLT. Significant differences were observed between the groups, statistically evaluated by chi-square test (***P < 0.001). (B) The high expression of miR-4634 was more frequent in primary tumors than metastasis tissue of NSCLC (P = 0.043). (C) Low expression of miR-4634 was significantly associated with short survival time of patients with NSCLC (P = 0.012). (D) Patients with LNM were more likely to have poor overall survival compared with patients without LNM (P < 0.001). (E) Patients with poorly differentiated cancer were more likely to have poorer overall survival than patients with well/moderately differentiated tumors (P = 0.010). (F) Patients with clinical stage I and II disease were more likely to have better overall survival than patients with clinical stage III tumors (P < 0.001). The survival curve graphs were performed using SPSS V19.0 (https://spss.en.softonic.com/).
