I bring it up because I'm suggesting that one possible explanation is that maybe this study is revealing yet remaining sexism in medicine. Just like the whole nonsense concept of hysteria, maybe professionals still discriminate by assuming women are just being "hysterical". Not consciously, but more as an artifact of western medicine and society.

I also strongly reccommend this fantastic podcast about the topic: http://www.maximumfun.org/sawbones/sawbones-hysteria

I hope this satisfies your question. I suspect I was just not clear enough that I was not legitimately suggesting hysteria as an actual explanation.
