Calculation of the pN3 patients using the optimal obtained cut-off values of eLNs using the X-tile software (A). Survival curves of the pN3 patients using the optimal cut-off values of eLNs: B patients with ≤ 31 eLNs vs. patients with > 31 eLNs; C patients with ≤ 20 eLNs vs. patients with > 20 and ≤ 31 eLNs vs. patients with > 31 eLNs; D patients with ≤ 31 eLNs vs. patients with > 31 eLNs after PSM analysis
