I agree with the top comment highlighting PCOS and trans men and women. It's a somewhat narrow view, but a valid comment.

The thing I took issue with was the claim that the article didn't say the very thing it says in the abstract.

The paper is actually very, very good, in my opinion. It starts from the observed premise that "women are less sensitive to anesthetic than men" and then digs in to find out why, building significantly on previous research. Also, the error bars on their graphs are so tight they're sexy.
