Figure 5. Experimental data of cell survival relative to control (S). It was a function of the initial extracellular concentration of ECA and the period of treatment. The symbols indicate experimental data and the curves were resulted from fitting the PD model to the data. ●: 2 h of constant ECA exposure; ▲: 6 h of constant ECA exposure; ◆: 24 h of constant ECA exposure; ◇: 72 h of ECA exposure. The best-fit values of the model constants are reported in Table 1.
