Currently, based on a published meta-analysis (including 89 studies) by our group , we are collecting and validating all data made available by the authors of the primary studies (prospective, published and unpublished). Up to this point, we have already received the data of 55 studies from more than 35 authors, including approximately 5500 patients. The study protocol  has been published in "Systematic Reviews" and is available as open access publication.
Future steps will include an update search in order to identify most recent studies, data analysis, and final presentation of the results, including the development of an online risk calculator to predict the risk of CAD.
As we proceed in the analysis and project, status updates will be available here.
