Does that mean, do you think, one could state when one was overdue enough to let them try induction "OK, i'll have the drip for 10 hours but if it doesn't work i'm going home again."?
Unfortunately, I think that the authors of this study are recommending that if active labour is not reached within 10 hours, straight to theatre - there is no point waiting. The reason for induction is to get the baby out ASAP (for whatever reason - regardless of whether it is valid) so it would be unlikely for 'them' to give up and let the baby stay in, IYKWIM.

This study gives me a funny feeling - without having read it. It just sounds ominous.
