The CD8+IFNγ+/million CD3+ values were higher in MISC_A compared to convalescent COVID-19 (p-value: 0.03) but were not significantly higher compared to MISC_C (p-value: 0.08) and compared to healthy controls (p-value: 0.08) (Supplementary Table S2) (Figure 1) (Supplementary Figure S3). This evidence concerns the gene CD8A and COVID-19.
