Abstract excerpt

INTRODUCTION: The FEN-COVID study identified 3 clinical phenotypes (PhA, PhB and PhC) in hospital-admitted patients with COVID-19, which were associated with mortality. The aim of this study is to validate the assignment to phenotypes and their association with mortality in two hospitals in Spain across the first 4 waves of the pandemic, including the impact of corticosteroids and anticoagulant drugs. METHODS: A...
