In the article Ellis, C. & Peach R.K., Racial-Ethnic Differences in Word Fluency and Auditory Comprehension Among Persons With Poststroke Aphasia, published in Archives of Physical Medicine and Rehabilitation, 2017;98:681-6 (DOI: https://doi.org/10.1016/j.apmr.2016.10.010), the wrong sample size was reported throughout the article and in Table 1. A new Table 1 is printed here. The Participants section of the abstract should read “Participants: PWA (N=290; 261 white and 29 black individuals).” The first 2 sentences of the Results section of the article should read “AphasiaBank contains data for 444 PWA (397 whites, 47 blacks) who were evaluated between 2008 and 2015. After excluding all PWA who did not have WAB-R scores, a final sample of 290 patients (261 whites, 29 blacks) was available for racial comparisons.”
