The expression of CDK2 was associated with various clinical features, such as Grade (Normal-vs.-Grade2, P = 5.088808E-03) (Figure 4C), the types of adenocarcinoma (Normal-vs.- Adenocarcinoma, P = 2.195E-02) (Figure 4D), gender (Male-vs.-Female, P = 1.338E-03) (Figure 4E), smoking habits (Normal-vs.-Smoker, P = 1.319E-11) (Figure 4F), stage (Normal-vs.-stage1, P = 3.458E-02) (Figure 4G), TP-53 mutation state (Normal-vs.-TP53 mutation, P = 1.624E-12) (Figure 4H), Weight (Normal-vs.-weight, P = 2.978E-2) (Figure 4I). This evidence concerns the gene TP53 and adenocarcinoma.
