Note: AH+, FEP with hallucinations; AH-, FEP without hallucinations; gFA, generalized fractional anisotropy; FEP, first-episode psychosis; HC, healthy comparison subjects.

^aAH+ were significantly smaller than AH- via Tukey’s Honestly Significant Difference (HSD).

^bAH+ were smaller than HC via Tukey’s HSD.
