found no
statistically significant association between labour induction and AFE
although some of the other associations (Caesarean delivery) remained
robust.28 The most important point of these studies is that even an
analysis of several million deliveries at a time might not produce consistent
associations, let alone permit cause and effect deductions. The
disease is rare, there are numerous confounding variables, and
although there may be a consensus about diagnostic criteria in the
medical literature, it is easy to surmise that this knowledge is not uniform
among practicing obstetricians.
