The fact that an intervention is listed in this glossary does not necessarily mean that we agree with its use. Nor does it necessarily mean that there is any scientifically valid or reliable evidence behind it.
Over time we hope to evaluate each of the interventions listed in this glossary, providing a ranking which tells you the level of scientific evidence which supports or does not support its use.
