Figure 5. Experimental data (as symbols, with standard error bars) and model fits (smooth curves) regarding the bioabsorption for zinc
provided as zinc oxide derived from four tablets (red, 69.6 mg/day), two softgels capsules (blue, 69.6 mg/day), or one softgel
capsule (orange, 34.8 mg/day). The data points are the average responses of the 15 subjects adjusted for any baseline drift
over the course of the study. The model fits are the result of minimizing the errors between the data points and curves at
the sampled times. Differences in responses are evident in the model-independent evaluations located in
Table 2 and
Table 3, the model-dependent visual comparisons, and the derived AUCs and percent absorbed located in
Table 4. Note the abscissa for this figure is t
1/2, so that the detail at the short time can be displayed.
