Figure 4. Competing Risks Regression of Hospital Discharge for Adults Hospitalized With COVID-19.

Figure 4.

Cumulative incidence of hospital discharge by vaccination status (fully vaccinated with a 2-dose series of mRNA vaccine vs unvaccinated) is shown for patients not immunocompromised (A), those immunocompromised (B), those aged 18 to 64 years (C), and those aged 65 years or older (D). The event of interest was discharge from the hospital before day 28 in the presence of the competing event of death. Patients who remained hospitalized more than 28 days were censored at 28 days. Competing risk models were adjusted for age group (18-49, 50-64, and ≥65 years), sex, self-reported race and ethnicity, and number of medical comorbidities (0, 1, 2, 3, and ≥4). Models by age group were adjusted for continuous age in years. mRNA indicates messenger RNA; and SHR, subdistribution hazard ratio.
