AVELLA-GARCIA, Claudia Bibiana. Systematic Evidence vs. Beliefs or Popular Knowledge: The Case of the Moon and Psychiatric Pathology. []. , 39, 2, pp.415-423. ISSN 0034-7450.

Introduction: It is important to consider the hierarchy that classifies the strength of evidence sources from the Evidence-Based Medicine point of view. This recognition should not put aside elements from the lower part of this scale. Method: In order to illustrate the proposed relevancy of all evidence levels, an example is used. The evidence that has been gathered on the subject of the Moon's influence on psychiatric pathology and the methodological difficulties that this topic implies are noted. Discussion and Conclusion: The methodological difficulties that can present themselves during the process of research and the way in which they can affect the evidence obtained are discussed. In turn, the evidence obtained should not be considered as absolute and incontrovertible knowledge. Additionally, possible designs for research on lunar influence on psychopathologic manifestations are suggested.
