Sponsor's own description

The aim of the study is to associate dose of thromboprophylaxis with outcome in critically ill COVID-19 patients. This will be done by associating dose of thromboprophylaxis with 28-day mortality, survival outside ICU, thromboembolic event and bleeding complications.This was done in our earlier study for patients admitted in March and April (Clinicaltrials.gov NCT04412304 June 2 2020) but now we will include the patients admitted in May, June and half of July and we will ad the outcome of 90-day mortality.
