Figure 4

Interaction plot of d, α, β, and γ with the output TNP. The 4 categorical variables referring to the parameters d, α, β, and γ are represented in the diagonal plots. The horizontal axis of each off-diagonal plot is the categorical variable on the diagonal vertically above the plot (if the plot is in a lower triangular position) or below the plot (if the plot is in an upper triangular position). The vertical axis of each off-diagonal plot is the tumor nanoparticle accumulation TNP.
