Blog en Sante presents the bottom line results of clinical studies on the efficacy of Non-pharmacological interventions (NPIs) (also called Complementary and Alternative Medicine), obtained through the use of rigorous Randomized Control Trial (RCT) methodology. We provide original studies, article reviews, medical society opinions and health authority recommendations. Each of our reviews describes a published scientific and medical fact; reading the original article is also recommended. Topic selection is based on relevance and on the quality of the methodology used in the study. To help readers, concept definitions are provided in the glossary section. The opinions expressed in this blog are solely those of the author. In accordance with our editorial charter, any comment posted on this blog attempting to steer readers away from conventional medicine or to deter them from following the advice of their physician will be deleted.
