The authors would like to call the reader’s attention to the following:

Unfortunately Reference 17 in the article was cited unnecessarily.

Equation 2 should read:

$$ \frac{K_d\left(1+{R}_1\right)+{\left[\mathrm{Apt}\right]}_1}{K_d\left(1+{R}_2\right)+{\left[\mathrm{Apt}\right]}_2}=\frac{1+1/{R}_1}{1+1/{R}_2} $$
