Dear Gwinyai,
if you prefer to avoid a discussion about the indications for C/section, you
can consider some hospital features as predictors instead (e.g.: public or
private; teaching hospital or else; number of beds of the obstetrics unit
grouped in different categories (0-10; .....); number of births per year
grouped in different categories; ...).
Kind regards,
Carlo

Carlo - thanks, i was skeptical about going into a discussion about the
indications for C/section which can be relative or absolute; maternal, fetal
or materno-fetal.

Austin - thanks for the link and pointing out that a pseudo R2 should not be
a worry. by increasing the sample size a thousand fold i guess what that
which is being detected is so small that in the end it's not worth it
(detecting something so small)?

Thanks all round. Appreciated.
