"The proper comparison to have made would be between women who attempt a natural birth, and women who have an elective Caesarean."
Quoting from the comment on the WHO statistics you link to Quietly.
I think the proper comparison between outcomes for birth would compare low risk women planning vaginal births having optimal care, with low risk women having elective c/s.
Optimal care according to the NICE guidelines involves women having one to one care throughout labour, intermittent monitoring, access to consultant input if labour becomes complicated, and access to fetal blood sampling in the case of suspected fetal compromise.
At present large numbers of low risk women giving birth in the UK don't have consistent access to these services, which are proven to improve outcomes for both mothers and babies.
And I'd like to see the comparison look at more than just immediate health outcomes for women and babies, but also to look at longer term outcomes, including subsequent pregnancies and births.
