Comparison of the simulated efficacy for different treatment strategies in moderate and severe cases.
a and b are the simulated efficacy of eight treatment strategies for moderate patients (ρ = 0.0005) and severe patients (ρ = 0.0025), respectively. Different colors correspond to treatment strategies. The table below the histogram shows the detailed values of the quadruple (ε1, ε2, ε3, ε4). “-” indicates that corresponding values are 0. Other parameters were given default values as shown in Table A in S1 Text.
