From: CHCHD2 is a potential prognostic factor for NSCLC and is associated with HIF-1a expression
Kaplan-Meier survival analysis of the NSCLC patients. The P-value was determined using the log-rank test. a Comparison of the overall survival (OS) between tumor size ≥5 cm and < 5 cm NSCLC patients. b Comparison of the OS of patients between well/moderately differentiated and poorly differentiated NSCLC tissues. c Comparison of OS between TNM Ia-IIa and IIb -IIIb NSCLC patients. d Comparison of the OS between lymph node metastasis and non-lymph node metastasis NSCLC patients. e Comparison of the OS between low CHCHD2 expression (−/+) and high CHCHD2 expression (++/+++) NSCLC patients. f Comparison of the OS between low HIF-1αexpression (−/+) and high HIF-1αexpression (++/+++) NSCLC patients
