In the article entitled “The Cost of Pediatric Stroke Acute Care in the United States” by Perkins et al,1 due to the Agency for Healthcare Research and Quality (AHRQ) data guidelines, no data observation involving less than or equal to 10 observations is to be published. In Tables 2, 3, and 4, there are some tabulated cells that violate this provision. The authors regret this error.
