Figure 2: Evaluating the prognostic impact of FBXW7 mRNA expression on disease-free and overall survival. Kaplan-Meier survival curves for breast cancer patients according to tumor expression of FBXW7 are presented. The patients from each cohort were divided into a group with High, Intermediate, or Low level of FBXW7 expression. The p values shown were obtained from a long-rank test among three groups. (a) Association of FBXW7 expression with disease-free survival. Dataset 1 to 10 in Table 1 were included in the analysis. (b) Association of FBXW7 expression with overall survival. Dataset 1, 4, 5, 9 and 10 in Table 1 were included. In other datasets were excluded due to that the information of overall survival was missing.
