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 4

Forest plot of risk ratio (RR) for evaluating the chemotherapy response rate in a fixed-effect model. The RR of chemotherapy response rate in Rg3 and chemotherapy group was compared with that of the chemotherapy group. Individual study is shown by the square with blue color, and the pooled datasets were shown by the diamond, representing the 95% confidence interval (CI) of each study. RR > 1 implied a better chemotherapy response rate of the experimental group. The size of each investigation represented the weighting factor (1/SE) assigned to the study.
