Dois novos estudos mostram que a enoxaparina não tem benefício na tromboprofilaxia primária de pacientes ambulatoriais sintomáticos com COVID-19.

Estudo 1: Enoxaparin for primary thromboprophylaxis in symptomatic outpatients with COVID-19 (OVID): a randomised, open-label, parallel-group, multicentre, phase 3 trial – The Lancet Haematology

Estudo 2: Thromboprophylactic low-molecular-weight heparin versus standard of care in unvaccinated, at-risk outpatients with COVID-19 (ETHIC): an open-label, multicentre, randomised, controlled, phase 3b trial – The Lancet Haematology

Early in the pandemic we wondered whether antithrombotic therapy in outpatients with #COVID19 would prevent #thrombosis ❓

Several trials were started globally and the ACTIV-4B trial was previously reported⬇️ https://t.co/Q15WcZwDIA

Now, we publish the OVID and ETHIC trials🧵
