Tornado diagrams for the FD group (a) and the LD group (b). Tornado diagrams analyzed all the parameters in this model. The length of colored bar for each parameter represents the extent of its effect on the overall survival. The longer a bar is, the larger its effect is. Abbreviations: NA_DT, age-specific mortality; ME_PRC, metastatic rate after underwent RC; FD_PD, rate of disease recurrence with worsening of the disease(FD group); DT_RC, mortality of RC surgery; DT_ME, death rate of metastatic state; LD_RE, rate of disease recurrence without worsening of the disease (LD group); LD_PD, rate of disease recurrence with worsening of the disease(LD group); FD_RE, rate of disease recurrence without worsening of the disease(FD group)
