Adjuvant chemoradiotherapy vs chemotherapy after R0 D2 gastrectomy for gastric cancer: Meta-analysis of randomized trials

Figure 2 Forest plot of disease-free survival/recurrence-free survival using the published Adjuvant Chemoradiotherapy in Stomach Tumors 2 CI (0. 663-1.421). Squares reflect inverse-variance weights; horizontal lines show study-level 95%CIs, and the diamond shows the restricted maximum likelihood pooled estimate with modified Knapp–Hartung inference. Hazard ratios below 1 favor chemoradiotherapy. N denotes the participants represented in each extracted comparison; The trial reported by Zhu et al[17] contributes 351 analyzed rather than 404 randomized participants.
