Multivariable mortality risk prediction using machine learning for COVID-19 patients at admission (AICOVID)

Abstract In Coronavirus disease 2019 (COVID-19), early identification of patients with a high risk of mortality can significantly improve triage, bed allocation, timely management, and possibly, outcome. The study objective is to develop and validate individualized mortality risk scores based on the...
