Meta-regression on mortality outcome adjusted for white blood cell count and blood lactate in studies comparing endovascular revascularization and open surgery (including revascularization and bowel resection alone) as initial treatment for patients with arterial occlusive AMI. Endovascular revascularization is taken as Reference, OR > 1 indicates higher mortality in the open surgery group. Squares and black lines with numbers indicate crude odds ratios (OR) with 95% confidence interval (CI). Green rhombs indicate adjusted OR and 95% CI. Adjustment was performed using the difference in the median white blood cell count (WBC) and in the median blood lactate between the groups under comparison in each study. AMESI study [3] results for this analysis were obtained from the original database. Heterogeneity, I-squared = 0.00%, Chi-squared test P-value = 0.304
