Principal component analysis score plots. (a) MCAO/R group vs. sham group, . (b) MCAO/R + EA group vs. MCAO/R group, . (X) is the interpretation of the model. Usually, higher than 0.5 is better. Abbreviations: EA: electroacupuncture; MCAO/R: middle cerebral artery occlusion-reperfusion; PCA: principal component analysis.
