Figure 4. Significant correlations of the severity of RSV infection with convalescent CMI responses (week 6). Data were derived from subjects with acute RSV disease. Severity of RSV disease was measured by the duration of hospitalization. Panel (A) shows stimulation indices measured by LPA (21 subjects). Panel (B) shows RSV-specific CD4+TNFα+% measured by flow cytometry (20 subjects). Coefficients of correlations and p values were generated using Spearman correlation analysis.
