Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Open Label Losartan | 34 patients with COVID-19 and respiratory failure participated in the study and were placed on losartan 25 mg once daily on study day 0. Losartan dose was increased to 50 mg once daily on study day 3. Participants continued losartan until they experienced resolution of respiratory failure (normal oxygen levels on room air), were discharged from the hospital, met stoppage criteria or completed 14 days of therapy.~Losartan: 25 mg QD from day 0 to day 3. Dose escalation to 50 mg QD until study completion | 2 | 30 | OG000 |
| Group 2 | External Controls | 46 external controls matched to losartan participants upon baseline characteristics. | 0 | 46 | OG001 |
