Figure 5 Forest plots of the risk ratio. A: Significant remission rate associated with middle-advanced stage upper gastrointestinal carcinomas; B: Effective rate associated with middle-advanced stage upper gastrointestinal carcinomas; C: Significant remission rate associated with middle-advanced stage upper gastrointestinal carcinomas; D: Effective rate associated with middle-advanced stage upper gastrointestinal carcinomas; E: One-year survival rate associated with middle-advanced stage upper gastrointestinal carcinomas. The box represents the RR point estimate of each study, and its area is proportional to the weight of the estimate. Horizontal lines represent the 95%CI. RR: Risk ratio; CI: Confidence interval.
