Hierarchical Regression Predicting the Reading Fluency Composite Scores.

RAN Variable	β	ΔR2	p
Mean Pause Time (MPT)	−.302	.073	<.001
Standard Deviation (SD)	−.323	.091	<.001
CV	−.140	.019	.067
mu	.025	.001	.741
sigma	.064	.004	.406
tau	−.322	.081	<.001

Note. In each of the six regression analyses, the Wechsler Intelligence Scale for Children – Fourth Edition (WISC-IV) Verbal Comprehension Index (VCI), Woodcock–Johnson Tests of Achievement – Third Edition (WJ-III) Basic Reading Standard Score, ADHD Symptom Severity, i.e., Conners’ Parent Rating Scale –Revised:Long (CPRS-R(L)) Scale N: DSM-IV Total Scale, and age were entered on the first step, followed by the RAN variable on the second step. In each analysis, the first step accounted for 59% of the variance in the Reading Fluency Composite. CV = coefficient of variation (SD/mean).
