Discussion-section attribution to Spencer et al. (2014), a large-scale study of over 400,000 first through third graders. The review of that prior work indicates intact vocabulary among SCD children is rare, contrasted with studies finding vocabulary-matched SCD groups.

"Spencer et al. (2014) found that the percent of children with SCD who also have intact vocabulary skills is around .1%."
