Fig. 3.
Comparison of TNM 8 and TNM 9 staging systems regarding overall survival. The graph shows that survival decreases as the stage increases in both staging systems. The tables show 3- and 5-year survival rates for each stage and p-values for comparisons. There was a statistically significant difference in OS between stage IIB and IIIA in TNM 8 and between stage IIA and IIB in TNM 9, with p-values of 0.04 and 0.034, respectively
