In the article “Defining an Intraoperative Hypotension Threshold in Association with Stroke in Cardiac Surgery” (Sun LY, Chung AM, Farkouh ME, van Diepen S, Weinberger J, Bourke M, Ruel M: Anesthesiology 2018; 129:440–7), errors were discovered in two references.
On page 445 in the first paragraph in the first line, the sentence starting with “In a randomized control study,” was incorrectly attributed to reference number 8 when it should have been attributed to reference number 9.
Also on page 445 the sentence starting with “Subsequently a MAP of no less” that starts at the bottom of the first column and continues into the second column was attributed to reference number 7 when it should have been attributed to reference number 8.
The authors regret the error. The article has been corrected online and in the PDF.
