Clinical summary: This meta-analysis suggests that direct oral anticoagulants (DOACs) | are effective. The heterogeneity of 25% 'might not be important'.

The quality of evidence supporting benefit is moderate to high for reduction in thromboembolism, low to very low for reduction in major bleeding, and low and low for DOACS increasing clinically relevant, non-major bleeding. We included randomized controlled trials of treating patients with DOACs compared to low-molecular weight heparin for cancer-associated thrombosis. Additional interpretations may be in the references in the 'Cited by' section below.
