Clinicopathological characteristics and survival outcomes of early-onset vs mid-aged gastric cancer using an evidence-based age cutoff

Figure 4 Kaplan-Meier curves for overall survival by pathological stage after inverse probability of treatment weighting. A: Stage I: 5-year overall survival (OS), 93.74% vs 92.19% in early-onset gastric cancer (EOGC) and mid-aged gastric cancer (M-GC), respectively (P = 0.056); B: Stage II: 5-year OS, 84.86% vs 77.62% in EOGC and M-GC, respectively (P = 0.225); C: Stage III: 5-year OS, 60.86% vs 43.75% in EOGC and M-GC, respectively (P = 0.120); D: Stage IV: 5-year OS, 14.29% vs 5.56% in EOGC and M-GC, respectively (P = 0.052). M-GC: Mid-aged gastric cancer; EOGC: Early-onset gastric cancer.
