Prognostic impact of lesser curvature lymph node count in stage I/II gastric cancer: A retrospective study

Figure 2 Determination of the optimal cutoff for lesser curvature lymph node count and its prognostic validation. A: Systematic evaluation of survival differences across candidate cutoff values (5-14 retrieved lymph nodes). The primary Y-axis (left) represents the statistical significance of the log-rank test expressed as -log₁₀(P-value). Higher values on the -log₁₀(P-value) scale correspond to greater statistical significance. The secondary Y-axis (right) shows the corresponding hazard ratio and 95% confidence interval derived from univariate Cox regression analysis for each cutoff; B: Kaplan-Meier overall survival curves for the entire cohort stratified by the optimal cutoff (≤ 7 vs > 7 retrieved lesser curvature lymph nodes).
