Fig. 13From: Stem cell-derived exosomes in the treatment of acute myocardial infarction in preclinical animal models: a meta-analysis of randomized controlled trialsSubgroup analysis showing the effects of the injection mode. After intramuscular injection of exosomes in patients with myocardial infarction, the improvement of LVEF in the exosome treatment group was significantly higher than in the control group (P = 0.000). Compared with the control group, the LVEF of the exosome-treatment group was not significantly improved after intravenous injection of exosomes (P = 0.061)Back to article page
