Ginsenoside Rg3 Serves as an Adjuvant Chemotherapeutic Agent and VEGF Inhibitor in the Treatment of Non-Small Cell Lung Cancer: A Meta-Analysis and Systematic Review

Figure 6

Forest plot of (hazard ratio) HR for evaluation of overall survival in fixed-effect model. The HR of overall survival in Rg3 and chemotherapy group was compared with that of the chemotherapy group. Individual studies are shown by the red-colored squares, and the pooled datasets are shown by the diamond, representing the 95% confidence interval (CI) of each study. HR < 1 implied improved overall survival in the experimental group. The size of each investigation represented the weighting factor (1/SE) assigned to the study.
