BAX and ischemic stroke: Due to the high heterogeneity of the 2 included studies (I2 = 99%, p < 0.01), a random effect model was used for data analysis, and the meta-analysis revealed this result: there was no statistically significant difference in the Bax protein expression level between the EA treatment group and control group, EA treatment could not reduce the Bax protein expression level in the animals with ischemic stroke [MD = −0.73, 95%CI (−1.68, 0.21), p > 0.05] (Supplementary Figure 1B).
