Article Snippet: A cohort study was conducted using data from the Optum de-identified COVID-19 electronic health record (EHR) data set; 1,271,033 adult participants were observed from February 1, 2020, to August 31, 2020, until their deaths due to COVID-19, deaths due to other reasons, or the end of the study.

Figure Lengend Snippet: Forest plot showing the hazard ratios (HRs) for each risk factor from the fully adjusted Cox proportional hazards model among COVID-19 patients (n=116,426). The values for race were separately ascertained by fitting a Cox proportional hazards model using only those with known race (n=89,027) and adjusted for all other covariates. The number of COVID-19–related deaths is slightly different from the full cohort (3136 among COVID-19 patients vs 3315 among the full cohort) due to failing or censoring on the same day as being diagnosed with COVID-19. eGFR: estimated glomerular filtration rate.
