RCT supports the use of therapeutic heparin in moderately ill patients admitted to the hospital with Covid-19.

Effectiveness of therapeutic heparin versus prophylactic heparin on death, mechanical ventilation, or intensive care unit admission in moderately ill patients with covid-19 admitted to hospital: RAPID randomised clinical trial – The BMJ

Related studies (some conflicting results)

RCT: Therapeutic-dose heparin superior to standard prophylactic or intermediate-dose heparins for thromboprophylaxis in high-risk hospitalized patients with COVID-19.

Another meta-analysis suggests standard-dose prophylactic anticoagulation is the best option for patients hospitalized with Covid-19.

M-A: Safety and efficacy of different prophylactic anticoagulation dosing regimens in critically and non-critically ill patients with COVID-19 – According to this analysis, standard-dose prophylactic anticoagulation should be the standard of care for hospitalized patients with COVID-19 who do not have an indication for therapeutic anticoagulation, irrespective of disease severity.

RCT: In noncritically ill patients hospitalized with Covid-19, therapeutic-dose anticoagulation with heparin increased the probability of survival to hospital discharge compared with usual-care thromboprophylaxis.

RCT: In critically ill patients with Covid-19, therapeutic anticoagulation with heparin did not result in improved outcomes compared to usual-care pharmacologic thromboprophylaxis.

RCT: In patients hospitalized with Covid-19 with elevated D-Dimer, a full-dose anticoagulation strategy based on rivaroxaban (full-dose heparins in unstable patients) + rivaroxaban to day 30 was not better than prophylactic anticoagulation and increased bleeding risk.
