Fig. 4: Meta-analysis of electroacupuncture effects on cognitive and memory performance in behavioral tests.

A The forest plot of the EA treatment effect on the number of platform crossings. B The forest plot of the EA treatment effect on the time spent in the target quadrant. C The random effects model’s SMD result for escape latency across multiple days, demonstrating a faster learning curve for mice receiving EA. D The forest plot for the effect of EA treatment on the discrimination index. The hour column represents the amount of time that the mice were put back into the same experiment box after the training. (SMD = (Treatment Group’s outcome – Control Group’s Outcome)/SD pooled).
