Andreas Calatzis: Revisiting a Widely Cited Study on Preoperative Screening for Primary Hemostasis Disorders
Andreas Calatzis, Managing Director of Eonis GmbH and Dynabyte GmbH, shared a post on LinkedIn:
“Happy weekend!
I’m pleased to share our new Perspective article in Frontiers in Medicine, coauthored with Michael Spannagl and Georg Wittmann.
We revisited a widely cited study on preoperative screening for primary hemostasis disorders, a study referenced in guidelines, in many reviews, and even prominently in the instructions for use of a popular platelet function analyzer.
Some weekend reading, if you would like to take a closer look:
- The original 2004 study
- Our Perspective
- A concise introduction to incorporation bias
I’m curious to hear your perspective on our ‘Perspective'”
