Michael Makris: Excellent Article in This Week’s NEJM Explains Word Estimand Clearly
Michael Makris, Emeritus Professor of Haemostasis and Thrombosis at the University of Sheffield, Editor-in-Chief of RPTH Journal, shared on LinkedIn:
“Do you know what is an “estimand”?
I had never heard of the word until today, but this excellent article in this week’s New England Journal of Medicine (NEJM) explains it clearly.
Essentially, it is the effect of actually taking a drug in a randomised trial. Although simplistically attractive there are good reasons why Intention to Treat (ITT) analysis should remain the gold standard. I can see estimands being used increasingly by manufacturers and sponsored speakers at meetings.”
