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

Figure 2 Kaplan-Meier curves for overall survival and recurrence-free survival in the overall study populations after inverse probability of treatment weighting. A: Five-year recurrence-free survival was 81.36% in the early-onset gastric cancer (EOGC) group and 72.10% in the mid-aged gastric cancer (M-GC) group [hazard ratio (HR), 0.59; log-rank P = 0.021]; B: Five-year overall survival was higher in the EOGC group (81.00% vs 75.71% in the M-GC group; HR, 0.58; log-rank P = 0.016). HR: Hazard ratio; CI: Confidence interval; M-GC: Mid-aged gastric cancer; EOGC: Early-onset gastric cancer.
