Figure 3.
Posterior distributions over the differences in standardized brain translocator protein levels (estimated using total distribution volume [VT]) between patients and control subjects and the additional effect of medication status (being medicated with antipsychotics or not at the time of positron emission tomography). The posterior distributions of medication effect are centered on zero and suggest that antipsychotic treatment does not affect brain VT after accounting for differences between patients with psychosis or schizophrenia and control subjects. ΔVT, difference in VT.
