Summary of disease outcomes of the two SARS-CoV-2 variant groups.
| Omicron variant N = 22,841 |
Delta variant N = 22,841 |
P-value | |
|---|---|---|---|
| N (%) | N (%) | ||
| Outcome-disease status | |||
| Mild | 20,681 (90.5) | 19,356 (84.7) | 2.2 × 10−16 |
| Moderate | 1308 (5.7) | 1467 (6.4) | |
| Severe/critical | 852 (3.7) | 2018 (8.8) | |
| Moderate or severe/critical outcome | 2160 (9.5) | 3485 (15.3) | 2.2 × 10−16 |
Moderate disease: Hospitalized but no intensive care unit admission; Severe/critical disease: intensive care unit admission or death with 28 days of positive test date
Comparisons between groups were performed using Pearson’s X2 tests. A two-sided P-value of < 0.05 was considered to be statistically significant. Adjustments for multiple comparisons were not made.
