2 min readAbout this topic
The BodySignals Library is written to answer common questions about posture, sitting, walking and back pain with the evidence behind each answer. This section explains how that works. The editorial policy covers who writes the articles, how topics are chosen and how commercial interests are kept apart from the content. The evidence levels page explains the labels you see on every article, from strong to expert opinion. The sources page lists every study and guideline cited across the library. The disclaimer sets out what general health information can and cannot do for you, and the corrections page explains how errors are reported and fixed. If something in an article looks wrong or out of date, this is where to find out how to tell us.
- Strong consistent results from trials and reviews
- Moderate good studies, some gaps
- Limited few or small studies
