Meta-analysis of overall survival rate after E75 vaccine injection: STATA 15.0 was used to analyze the five clinical studies. The relative risk (RR) value and the 95% confidence interval (CI) were used to describe the effect of the vaccine on vaccinated and control patients. Heterogeneity was tested using the Q measurement method (P = 0.476) and the I2 measurement method (I2 = 0.0%). A meta-analysis of the overall survival rate of 335 patients in the vaccinated group and 287 patients in the control group showed that the overall survival rate was not different between the two groups (P > 0.05)
