Notes: HC-healthy control; Asym-asymptomatic; Sym-symptomatic; SA-sub-acute; EC-early chronic; AT-attention; PS-processing speed; EF-executive functioning; WM-working memory; VM-verbal memory; eff-partial eta. All values are covariate-adjusted for WRAT-4 word reading.

^*Indicates significance. Bonferroni corrected level of 0.01. All cognitive measures are norm-referenced T-scores except for VM which uses raw scores.
