  • [pre-print, not peer-reviewed] Based in a case-control study (872 hospitalized COVID-19  patients and 3,488 controls) and a cohort study (1,827 adults admitted with COVID-19) conducted among inner–city adult residents in London, Black and Mixed/Other ethnicity were associated with a significantly higher admission risk than white ethnicity (OR=3.1, 95% CI 2.6-3.7 and OR=3.0, 95% CI 2.3-3.9, respectively). Among patients hospitalized for COVID-19, 29% died over a median of 8 (IQR 4-16) days and Black and Mixed/Other ethnicity were both associated with non-significantly lower risk of mortality.
