I learned about this recently! It's wild how big the difference is. Even though legal/practical barriers to gender equality in medicine and data collection have been virtually nonexistent for the past few decades the inertia from the decades before that (where women were often specifically excluded, among many other factors) still weigh heavily.

To any women who happen to be reading this: if you can, please help fix this! Participate in studies, share your data when appropriate. If you see how a process can be improved to be more inclusive then please let it be known. Any (reasonable) male knows this is an issue and wants to see it fixed but it's not clear what should be done.
