 - MD differed significantly in the left superior cerebellar peduncle (SCP) between the SZ and HC groups (p<0.05), but not between the ADHD and HC groups or BD and HC groups.
 - Individuals with SZ had lower MD in this tract than the matched controls (as indicated).
 - This finding held after adding medication as a covariate (haloperidol equivalent dosage).

-<div style="font-size:48px">
-- We found decreased MD in the left SCP, a component of the CTC.
-- These results appear in line with previous fMRI results that found increased functional connectivity in the CTC in individuals with SZ. [@Cao2018]
