Figure 4 Validation of the 7-lymph-node cutoff in subgroups. A-C: Systematic evaluation of candidate cutoffs (5-14 nodes) in the N0 (A), N+ (B), and T3 (C) subgroups. The red highlight indicates that 7 lymph nodes was the threshold with the greatest hazard ratio among significant cutoffs (log-rank P < 0.05) in each subgroup; D-F: Corresponding Kaplan-Meier survival curves stratified by the 7-node cutoff (≤ 7 vs > 7) within the same N0 (D), N+ (E), and T3 (F) subgroups.
