Abundance of ILCs, but not of CD16+ NK cells, CD4+ T cells, or CD8+ T cells was associated with odds of hospitalization: the odds ratio for hospitalization, adjusted for age, sex, diagnosis of diabetes mellitus, and symptom duration, was 0.454 (95%CI: 0.213–0.808; p = 0.018), an increase of 54.6% for each twofold decrease in ILC abundance (Table 3). This evidence concerns the gene CD8A and diabetes mellitus.
