  1. Categorical variables were tested using Fisher's Exact Test and p values are reported. Continuous variables were tested using t tests and p values are reported with 95% confidence intervals.
  2. CI = Confidence interval. SD = Standard deviation. PPVT-4 = Peabody Picture Vocabulary Test. EVT-2 = Expressive Vocabulary Test. WNV = Wechsler Non-verbal Scale of Ability.
