Absolutely agree with this, Dory. In addition, the problems of the TBT are huge (even if not related to intention to treat analysis).

The participation of centres which didn't have high vaginal breech rates before the trial, so effectively on a learning curve in the course of the trial. The surprising finding that 2 years down the line, the long-term morbidity is higher in the CS arm - which rather evens things out. Cronk et al would cite the missed opportunity to compare upright posture with dorsal. The fact that the statistically significant reduction in intrapartum/neonatal deaths with planned CS of TBT is misrepresented by reg as "breech is very dangerous and your baby is likely to die".

And the consequence is that registrars (and midwives) are, on the whole, now much less experienced in breech delivery - so it's something of a self-fulfilling prophecy.
