The editor and publisher of Nature and Science of Sleep have retracted the published article.
Following publication, concerns were raised regarding the methodology of the described melatonin production, timing and the quantification.
When the authors were contacted for an explanation, they cooperated fully with the investigation, but were unable to address the concerns raised.
As the validity of the methodology is integral to the scientific integrity of the article and the editor and publisher have been unable to determine the validity of the methodology, we are therefore retracting the article. The authors disagree with the retraction.
We have been informed in our decision-making by our editorial policies and the COPE principles.
The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as ‘Retracted’.
