Systemic inflammatory response index is a predictor of prognosis in gastric cancer patients: Retrospective cohort and meta-analysis

Figure 1 Literature screening flowchart.

Figure 2 Meta-analysis prognostic forest plot. OS: Overall survival; DFS: Disease-free survival.

Figure 3 Effect of systemic inflammation response index score on prognosis in patients with robotic gastrectomy. A: Effect of systemic inflammatory response index (SIRI) on overall survival in patients; B: Effect of SIRI on disease-free survival in patients. P value was calculated by the log-rank test. SIRI: Systemic inflammatory response index.

Figure 4 Effect of systemic inflammatory response index score on overall survival and disease-free survival in different subgroups of patients with robotic gastrectomy. A: Overall survival (OS) of patients in the low age group; B: Disease-free survival (DFS) of patients in the low age group; C: OS of patients in the high age group; D: DFS of patients in the high age group; E: OS of patients in the tumor-node-metastasis (TNM) I-II group; F: DFS of patients in the TNMI-II group; G: OS of patients in the TNMIII group; H: DFS of patients in the TNMIII group; I: OS of patients in the postoperative group with no or minor complications; J: DFS of patients in the postoperative group with no or minor complications; K: OS of patients in the postoperative group with severe complications; L: DFS of patients in the postoperative group with severe complications (P value was calculated by the log-rank test). SIRI: Systemic inflammatory response index.
