Figure 1
Figure 1 Number of examined lymph nodes was categorized into subgroups. The bars in the graph reflect the percentage of patients who fell into each subgroup. Entire cohort, n = 893; stage I, n = 228; stage II, n = 444; stage IIIA, n = 221.

Figure 3 Overall survival curves for the entire cohort and the stage I, II, and IIIA groups and optimal dichotomization by the number of examined lymph nodes. A: Stage I, LN = 4, P = 0.004; B: Stage II, LN = 4, P ≤ 0.001; C: Stage II, LN = 5, P ≤ 0.001; D: Stage IIIA, LN = 6, P = 0.019; E: Entire cohort, LN = 4, P ≤ 0.001; F: Entire cohort, LN = 5, P ≤ 0.001; G: Entire cohort, LN = 6, P < 0.001. LN: Lymph node.
