Evaluation of Melatonin Therapy in Patients with Myocardial Ischemia-Reperfusion Injury: A Systematic Review and Meta-Analysis

Figure 5

Forest plot of subgroup analysis according to the timing of melatonin administration on infarct size (proportion of the LV mass (a) as well as the grams (b)), and cumulative meta-analysis according to the duration of ischemia-reperfusion on infarct size (proportion of the LV mass (c) as well as the grams (d)). CI: confidence interval, i.c.: intracoronary injection, i.v.: intravenous injection, I/R: ischemia-reperfusion, p.o.: orally treated, and : heterogeneity -value.
