Research references are listed, as nearly as possible, by the dates on which the research was first published or brought into the public domain.
Clicking on the title of the research will take you either to a precis of the findings (with further links to the relevant source material) or directly to that source material.
Because many original research papers remain restricted by publishers it is not always possible to link visitors to the original research so the links that we give will normally be to the 'second level' reports from reliable and respected sources such as MedicalNewsToday, WebMD, MedPage Today and Medscape.
If you wish to pursue your own researches beyond these pages, one of our regular contributors, John Scott, has some suggestions for sites which will provide you with reliable and informative material.
