Additionally, consistent with the finding in adults hospitalized with COVID-19 (Figure 3C and Table 4), after accounting for effect of group, each twofold decrease in ILC abundance in pediatric patients hospitalized with COVID-19 or MIS-C was associated with a 40.5 mg/L increase in blood CRP (95% CI: 77.87–3.13; p = 0.035) (Figure 4C), and no such association was detected with CD4+ T cells, CD8+ T cells, or CD16+ NK cells. This evidence concerns the gene CRP and COVID-19.
