Fig. 6.

Normalized sensitivity coefficients (NSC) over four modeled time points (2, 4, 7, and 10 d) for: (A) total plasma T3 concentration, (B) total plasma T4 concentration, (C) total follicular cell (thyrocyte) number, and (D) the amount of MIT in the thyroid lumen. Only parameters showing NSCs $>|0.25|$ in any of the four time points are displayed. Parameters with NSCs $<|0.25|$ in all timepoints and for all variables were removed for the sake of clarity. Please see text and Table 1 for definitions of abbreviations.
