Randomized controlled trials (RCTs) and observational studies that reported the differences in the outcomes of AP for patients receiving anticoagulants (intervention group) in addition to the standard of care (SOC), compared to patients managed by SOC alone (control group), were eligible. A random-effects model was used to calculate the pooled odds ratios (OR) and mean differences (MD) with the corresponding 95%-confidence intervals (CI).

Except one, all studies reported on low-molecular-weight heparin (LMWH). Both RCTs and observational studies reported results in favor of the LMWH group. Subgroup RCTs\u2019 analysis revealed significantly decreased odds of mortality [OR 0.24; 95%CI 0.17\u20130.34] and multiple organ failure [OR 0.32; 95%CI 0.17\u20130.62] in the intervention group. Moreover, the need for endoscopic or surgical interventions [OR 0.41; 95%CI 0.28\u20130.61] were significantly reduced by LMWH. The subgroup analyzes for moderate and severe cases, respectively, yielded similar results.
