Forest plot to study the effect of PE on cardiac troponin I (cTnI). PE reduced serum cTnI levels in MIRI animals compared to control group (SMD = −3.66, 95% CI: −4.54 to −2.79, p < 0.001). The dark squares represent the standardized mean difference (SMD) for each study. The diamonds represent the pooled SMD. 95% of the CIs are indicated by lines. The analysis was conducted using a fixed-effects model.
