Brackets indicate analyses using a mixed effects model with score as the dependent variable, group as the between-subjects factor (family identifier nested within it as a random effect), and relationship to proband and relationship to proband-by-group as fixed effects.
Broad Reading = Letter-Word Identification and Passage Comprehension, Basic Reading = Letter-Word Identification and Word Attack
