Note. Risk ratios in boldface are statistically significant (95% confidence interval does not include 1). In cases where the lower bound of the confidence interval was 1.0 after rounding, risk ratios were considered significant if the value was rounded down to 1.0, but not if it was rounded up to 1.0. CI = cochlear implant; BRIEF = Behavior Rating Inventory of Executive Function.
