Notes: RT = reaction time; CPRS-R = Conners' Parent Rating Scale, Revised; GORT-IV = Gray Oral Reading Test-IV; WJ-III RF = Woodcock–Johnson-III Reading Fluency; TOWRE = Test of Word Reading Efficiency.
*Significant ΔR2 values represent generally medium effect sizes.
**Significant ΔR2 values represent generally large effect sizes.
