Figure 2. Analysis of lung adenocarcinoma patient survival using the Kaplan-Meier method.

(A) The high MAGE-A9 expression group (green line) has a significantly lower survival rate than the low/no MAGE-A9 expression group (blue line). (B) Overall survival in female cases was significantly longer than in male cases. (C) Overall survival in cases with no lymph-node metastasis was significantly longer than in cases with lymph-node metastasis. (D) Survival curves based on differentiation. Differentiation = 1 is the well-differentiated group (blue line); differentiation = 2 is the moderately differentiated group (green line); differentiation = 3 is the poorly differentiated group (brown line).
