Forest plots of all trials investigating the effect of injectable hydrogel combination therapy on ejection fraction and fractional shortening outcomes in myocardial infarction treatment outcome studies (a. Rats EF, b. Mice EF, c. Rats FS, d. Mice FS). Data are expressed as weighted mean differences with 95% CIs, using generic inverse-variance random-effects models. Between-studies heterogeneity was tested by using the Cochran Q statistic (chi-square) at a significance level of P < 0.05. Reference numbers for each study can be found in Table 1 and list of references
