"On the average, half of the deaths caused by war happened to civilians, only some of whom were killed by famine associated with war...The civilian percentage share of war-related deaths remained at about 50% from century to century."
That implies roughly 3/4 of the deaths are men.
UNICEF et al cover this at length. https://www.unicef.org/graca/patterns.htm
Edit: Intersting discussion here, suggesting much of the difference comes down to how you measure and when you stop measuring. The longer you measure, the worse it is for civilians and in particular, women. https://files.prio.org/Publication_files/Prio/Armed%20Confli....
Not does that alone justify keeping them in poverty.
The mainstream opinion today seems to be that the current "mix" is less favorable to women (I happen to disagree with this), but I think it is a good basis for a civil discussion, more so than the insistence on equality at all levels which seems unattainable to me. (EDIT: last few words added)
At least historically, what society gave in return was keeping women (for the most part) out of harms way when it came to wars.
