Supplementary Table 1 displays CI simulations showing the spectrum of effect levels in NFV and BZ combinations. The CI values for experimental data are depicted through Fa-CI plots in Figures 1B and 1D. Supplementary Figures 1 to 6 provide detailed results on NFV and BZ combination studies in cell lines and xenograft tumor lysates, exploring synergistic, additive, or antagonistic effects.

Presentation Transcript
Supplementary Table 1 A. CI simulations display synergism (CI < 1), additive effect (CI = 1), or antagonism (CI > 1) for the entire spectrum of effect levels (Fa) in the combination of NFV and BZ (right panel). CIs for experimental values (left panel) are displayed as actual Fa-CI plots in Figure 1B. B. CIs for experimental values are displayed as actual Fa-CI plots in Figure 1D.
