Metaregression provided valuable information regarding the interaction between the continuous covariates and treatment effect of resveratrol in reducing the infarct size and may explore the source of heterogeneity. Consistent value showed that none of the covariates below had an impact on the cardioprotection of resveratrol in myocardial I/R injury.
