Kaplan-Meier plots for ccRCC patients. A Overall survival in different stage groups. The mortality rates of the two groups show a downward trend, which decreased rapidly at the beginning and then leveled off. The red curve represents the late-stage group, blue curve represents the early-stage group. B PSAT1 expression level about late-stage patients for overall survival. The mortality rates of the different expression level showed a downward trend, which decreased rapidly at the beginning and then leveled off. The blue curve represents the high-expression, green curve represents the low-expression. Follow-up time for horizontal axis and vertical axis for survival rate. Survival curves were obtained by linking the corresponding survival rates at each time point. G1: late-stage group; G2: early-stage group. p < 0.05 was considered statistically significant
