Figure 6

Scatter plots with model fits between the viral levels and immune response parameters. a and b give the scatter plots with linear fits between the viral levels and the neutralizing efficiency h₁ of antibodies at time t=10 and t=100, respectively. The circles are the data points and the line is the linear fit. In Figure 6a, a negative relationship between the viral levels and the antibody neutralizing efficiency is observed. Figure 6b shows a positive relationship between the viral levels and the neutralizing efficiency. c-d give scatter plots with linear fits (correlations) between the viral levels and the probability of proliferation of B cells ψ, at time t=10 and t=100, respectively. Figure 6c shows a negative relationship between the viral levels and the probability of proliferation of B cells. In Figure 6d, a positive relationship between the viral levels and the probability of proliferation of B cells is observed. The parameter values used are given in Table 1 and the initial conditions were $D_0=100,P_0=100,Q_0=100,V_0=100,T_0=750,T_0^{\ast }=100,C_0=1,B_0=1$.
