Table 3. Hierarchical Regression Analyses Predicting Language Ability.

Results of the hierarchical multiple linear regression models used to predict naming vocabulary (EOWPVT scores) and overall language ability (CELF-IV-CL scores) from FC for IFG and WA connections (IFG L-WA L, IFG L-IFG R, WA L-WA R).
