To limit the number of analyses, a subset of tests were selected a priori based on their ability to assess cognitive domains impaired following RHI exposure [8, 9, 53]
All statistical analyses used neuropsychological test raw scores
In order to describe the clinical sample, neuropsychological test raw scores were converted into standardized scores accounting for age, sex, and/or educational attainment. Raw BRIEF-A BRI scores were converted into standardized age-adjusted T-scores
Before analysis, Trails A and B were reverse coded to correct directionality (i.e., lower scores represented worse performance).
