Stratified by racial and ethnic groups, age-adjusted odds ratios for primary COVID-19 outcomes in the second wave cohort relative to the first wave cohort.
In the second wave, all racial and ethnic groups (A-D) had lower risk of mortality (OR < 1, 99·5% CI < 1) relative to the first wave. However, Black (C) and Hispanic (D) COVID-19 patients had more improved COVID-19 outcomes, including lower risk of hospitalization and acute kidney injury than White (A) and Asian (B) COVID-19 patients. More detailed information with exact odds ratios and 99·5% confidence intervals can be found in Supplemental Table 1.
