Hierarchical regression predicting WJ-III Passage Comprehension (N = 232): nonword reading, general word reading, and exception word reading together explained 10.7%; expressive vocabulary added a significant 16.4% unique variance at the final step (Table 4).

"When expressive vocabulary was added to the model in the final step, it significantly explained 16.4% of the unique variance."
