Figure 2 Impact of Intracoronary Cell Therapy on Left Ventricular Remodeling
Forest plots show the significantly beneficial impact of cell therapy after myocardial infarction on (A) left ventricular ejection fraction (EF), (B) end-systolic volume (ESV), (C) end-diastolic volume (EDV), and (D) infarct size/functional defect at myocardial scintigraphy or late enhancement at magnetic resonance imaging. CI = confidence interval; I2 = inconsistency; SE = standard error.

Figure 3 Metaregression Between Injected Volume and Left Ventricular Remodeling
L'Abbé plot shows the overall trend toward a statistically significant association between average volume injected in the culprit coronary artery and average change in left ventricular ejection fraction (LVEF) across included studies (squares), with the size of each square proportional to sample size. This trend supports the presence of a dose-response relationship.
