CD14 and COVID-19: We analyzed the correlation between all COVID-19 convalescent patient samples and age, and found CD14 Mono increases with age in the convalescent COVID-19 patients (r=0.7294, p=0.0019), but CD14 Mono (NFKBIA) has no significant correlation with age (r=0.3153, p=0.1530) (Figure 2C).
