Interestingly, postinfusion HA-specific FcγRIIa-binding antibody, FcγRIIIa-binding antibody, and NK cell activation were associated with worse odds of a favorable d5 clinical outcome in patients with severe A/H1N1 influenza using both univariate and multivariate proportional odds regression models (Figure 6, B and D; right side of heatmap). The gene discussed is FCGR3A; the disease is influenza.
