NCAPG and adenocarcinoma: Kaplan-Meier survival analysis showed that NCAPG expression was negatively correlated with survival in NSCLC patients (Fig. 2B, n = 156, p = 0.003), particularly in elderly patients (≥ 60 years old) (Fig. 2C, n = 84, p = 0.0022), adenocarcinoma (Fig. 2D, n = 92, p = 0.0239), and squamous cell carcinoma (Fig. 2E, n = 43, p = 0.0296).
