Wow they actually linked the study! https://jamanetwork.com/journals/jamasurgery/article-abstract/2786671?utm_campaign=articlePDF&utm_medium=articlePDFlink&utm_source=articlePDF&utm_content=jamasurg.2021.6339

Thanks for sharing this, this paper was an interesting read. That stat is only part of the story. Women were consistently less likely to die if the surgeon was female, and men were also more likely to die if the surgeon was male. Also, across the board, women were consistently less likely to die than men regardless of surgeon sex. That was surprising to me seeing how how medicine has largely ignored women's health for a long time. This seems to point either to a difference in treatment quality between men and women surgeons, or a difference in the risk level of surgeries performed by men and women surgeons. I'd be really interested to look more into the mechanism driving this disparity.
