The analysis of survival curves based on follow-up data for patients with lung cancer revealed that statistically significant differences in DFS for individuals with greater lncRNA AATBC, and NSE than those with lower lncRNA AATBC expression, and NSE concentration (P = 0.036, 0.026 respectively) as well as for patients with lower lncRNA Sirt1-AS than those with higher expression (P = 0.014) (Table 4; Fig. 6). Here, SIRT1 is linked to lung cancer.
