"After all factors were taken into account there was a stronger link with emergency caesarean than with pre-planned ones, although the numbers were small for this calculation."
What numbers were small? For what calculation? Pre-planned link not statistically significant? Or the number of degrees of freedom remaining is fewer than required by the calculation to be valid?
Since they start warning off everyone that c sects MAY have a higher risk of obesity ....
and the way they phrase their findings and what is missing entirely, I would need to spend a lot of time looking in detail at their stats to feel comfortable, maybe need to run more analyses.
Where is the comparison between the pre-planned C sect vs non-Csect, is there a statistically significant risk, large or small, is it 40% or 4%?
For a sanity check, same for emergency C-sect vs non-csect.
The vague sentence could even be true if the stronger link were small and not significant.
I am nearly to the point not to trust any study like this, unless I personally know and trust at least one of the authors.
