Fig. 3

A prognostic risk model was constructed from the 7-gene signature, and the horizontal axis represents the high-risk and low-risk groups. A Distribution of the 7-gene signature risk score. The samples were grouped by the median risk score. The vertical line in the middle of the x-axis represents the high-risk and low-risk group boundaries: the left is the low-risk group, and the right is the high-risk group. Green represents the low-risk group, and red indicates the high-risk group. B The OS of BC patients in the high-risk and low-risk groups. Survival state and time corresponding to different risk scores in (A). Green indicates the patient was alive at follow-up, and red indicates already deceased. C Expression levels of 7 genes in the high-risk and low-risk groups. Green represents lower expression while red indicates higher expression. BC, bladder cancer; OS, overall survival
