Figure 2 | Serum levels of TSH and free T4 in a large series of patients with central hypothyroidism investigated in our institution. Serum levels of TSH (logarithmic scale) and free T4 in a large series of patients with central hypothyroidism investigated at Ospedale Maggiore Policlinico, Milan, Italy. Each blue circle represents one patient, and the area between the dashed lines represents the normal range of TSH (mU/l) and free T4 (pmol/l) in the serum. The lack of correlation between the levels of TSH and free T4 is consistent with the reduced bioactivity of circulating TSH molecules. Data from Ref. 25.
