Note: Sample sizes at follow-up are noted parenthetically. R² reported for full model with GRTR and both covariates entered; models run with simultaneous entry. PPVT-R-SS = Peabody Picture Vocabulary Test–Revised–Standard Score; EOWPVT-SS = Expressive One-Word Picture Vocabulary Test–Standard Score; CTOPP = Comprehensive Test of Phonological Processing; PA = Phonological Awareness; RN = Rapid Naming; PM = Phonological Memory.
