Letter to the Editor
Because this piece does not have an abstract, we have provided for your benefit the first 3 sentences of the full text.
We thank Dr Bagley for his comments on our article. We agree that a larger sample size would have been optimal; however, given that the predictors included in the models were not altogether independent of one another (eg, the cognitive measures have substantial intercorrelations), the number of truly independent factors tested was—to some degree—reduced. Nonetheless, as we acknowledged in the article, there is always a possibility that a study with negative findings is underpowered to detect a true effect.
