Age, sex, intracranial volume, daily antipsychotic dosage and scanning site were entered as covariates.
ARMS, at risk mental state; HC, healthy controls; NP, did not develop psychosis; P, developed psychosis; PT, planum temporale; SD, standard deviation. The Bold values indicate significant main effects. *Did not reach a statistically significant level.
