Fig. 12From: 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 therapy timing. Compared with the control group, exosome therapy at 0 (P = 0.000) and 60 (P = 0.006) mins after myocardial infarction significantly improved LVEF. Exosome therapy 30 min (P = 0.071) after myocardial infarction did not significantly improve LVEFBack to article page
