Figure 4.

Comparison of low frequency permittivity (${\epsilon }_l$) (a), conductivity (${\sigma }_{\mathit{DC}}$) (b), dispersion broadening parameter ($a$) (c), and dielectric relaxation time constant ($\tau$) (d) of the experimental data from measurements with blood samples of varying HES concentration. The displayed data is for time point $t=100s$. Results are shown using box plots. One-way ANOVA with Tukey’s post-hoc test is used for multiple comparison. Probability values are indicated on figures by asterisks, as follows: *p < 0.05; **p < 0.01, ***p < 0.001, ****p < 0.0001.
