Full-dose blood thinners reduce the need for organ support in moderately ill COVID-19 patients, but not in critically ill patients

A large clinical trial conducted worldwide shows that treating moderately ill hospitalized COVID-19 patients with a full-dose blood thinner reduced their need for organ support, such as mechanical ventilation, and improved their chances of leaving the hospital. However, the use of this treatment strategy for critically ill COVID-19 patients requiring intensive care did not result in the same outcomes.
