This systematic review and meta-analysis serve the purpose of comparing the mortality associated with the intensity of anticoagulation in patients admitted with covid-19.Methods: A total of 7120 patients were recruited in 11 studies comparing using prophylactic anticoagulants against therapeutic anticoagulants.Results: Our study showed that using prophylactic anticoagulants was associated with a 42% reduction in mortality compared to therapeutic anticoagulants (OR 0.58 (95% CI:0.676-0.499), p=0.000). Also, we assessed mortality in patients using no anticoagulants against using prophylactic anticoagulants. A total of 6069 patients were recruited in 4 studies in which 2 studies significantly favored prophylactic anticoagulants in terms of reducing mortality. Cumulatively, the meta-analysis showed that using prophylactic anticoagulants was associated with a 5% reduction in mortality but without any statistical significance: (OR 1.049 [95% CI 1.237 - 0.865]) (p=0.626).Conclusion: Our meta-analysis favors using prophylactic anticoagulation in covid-19 patients reduces all-cause mortality in comparison to therapeutic anticoagulation however the impact on mortality when compared with no anticoagulation was not significant.PROSPERO Number: CRD42021257320 %U https://smj.org.sa/content/smj/43/6/541.full.pdf
