So, if you find that, for example, vaginal breech birth increases the risk of bruising to 2. It is twice the rate of bruising. Keep in mind that figures must be examined from every angle. You can present the same information many ways and get very different reactions and perceived outcomes. Remember what Mark Twain said the three kinds of lies are: lies, damned lies, and statistics. Reactions to the Term Breech Trial Here are some professional opinions regarding the study.
This article states that the TBT has made too sweeping a change for something that has so many variables. Read part of his commentary at the link below full text requires subscription. Inappropriate use of randomised trials to evaluate complex phenomena: case study of vaginal breech delivery by Andrew Kotaska, MD.
After the sweeping change came around from the TBT, doctors and researchers in parts of the world where vaginal breech birth was still common wanted to see if they observed a more favorable outcome for vaginal breeches. They did.
Read the summary below to see how vaginal births in France and Belgium were just as safe as planned cesareans. The vaginally delivered group of children were in slightly better health at two years old. Here is another review of the TBT. A word about studies and statistical figures: As Dr. Mothers and infants were followed-up to 6 weeks post partum. The primary outcomes were perinatal mortality, neonatal mortality, or serious neonatal morbidity; and maternal mortality or serious maternal morbidity.
Analysis was by intention to treat. Findings: Data were received for women. Originally, the research was going to continue for five years, but the researchers decided to stop the trial early and publish the results, because they felt that the data was showing that caesarean section was a far better and safer option than vaginal birth for breech babies.
Almost as soon as it had been published, however, other researchers, practitioners and consumer groups began to spot problems with the methods that had been used to carry out the research.
They realised that there were so many issues with the way in which the research was designed and carried out that its findings could not be relied upon. People started to publish critiques and articles discussing these, and the conversation grew and grew.
The concern was international, and although the authors tried to defend their work, most people now believe the results of this trial to be of little value. Change is now happening, though it is a slow, uphill battle in some areas.
For most of these women, the approach to delivery is controversial. We did a randomised trial to compare a policy of planned caesarean section with a policy of planned vaginal birth for selected breech-presentation pregnancies. METHODS: At centres in 26 countries, women with a singleton fetus in a frank or complete breech presentation were randomly assigned planned caesarean section or planned vaginal birth.
Women having a vaginal breech delivery had an experienced clinician at the birth. Mothers and infants were followed-up to 6 weeks post partum. The primary outcomes were perinatal mortality, neonatal mortality, or serious neonatal morbidity; and maternal mortality or serious maternal morbidity. Analysis was by intention to treat. Of the women assigned planned caesarean section,
