Significant correlations between diffusion parameters and ASD symptom scores.

	Total SCQ score
Right inferior CST: FA	0.506 (p = 0.038)**
Right inferior CST: MD	−0.395 (p = 0.117)a
Right inferior CST: RD	−0.542 (p = 0.025)**
Right inferior CST: AD	0.120 (p = 0.647)

All other figures are Pearson's coefficient. Italics — post-hoc tests of correlations with subscale scores. SCQ — social communication questionnaire. CST — corticospinal tract. FA — fractional anisotropy. MD — mean diffusivity. RD — radial diffusivity. AD — axial diffusivity.

^**Significant at p < 0.05 (2-tailed).
