Re studying only women: it's a problem when you are making a claim about all cause mortality but failing to mention that it's all cause mortality "in women", you can't generalize.

"Are you saying that the authors didn't control for them (then why collect data on them and include it?), or that they did so badly (why do you think that), or something else"

Yes, I addressed this above, see my comment on residual confounding, amongst my many other criticisms.
