Striatal D2/3R availability for TRD, TRD AP and healthy control subjects.

<p>Striatal D2/3 receptor (D2/3R) availability of TRD patients, TRD patients with antipsychotics (TRD AP) and healthy control subjects. The black dots represents the striatal D2/3R availability of each subject. The horizontal lines indicate the mean D2/3R availability of each group which is 0.84 for the TRD, 0.50 for the TRD AP and 0.81 for the healthy control subjects.</p
