Objectives: The WHO designated individuals with low oxygen saturation, SpO2<94%, as severe SARS-CoV2 infection (COVID-19) and recommendations to seek care in a hospital setting were advised. A rapid, office-based method to select patients with severe COVID-19 who need intensive care was necessary during the peak of the pandemic.

Design, Setting And Participants: This is a prospective cohort study of patients with confirmed severe COVID-19 between September 2020 and April 2021.

There is a need for developing systems biology approaches to integrate comprehensive genetic information and provide new insight on T2D biology.
