The iron-heart disease connection: is it dead or just hiding?
Abstract
More than 20 years ago it was proposed that differences in body iron stores may account for differential heart disease prevalence in men and women. In 1992 Finnish investigators presented intriguing supportive evidence for this proposal by showing that middle-aged men with normal but elevated serum ferritin, a biomarker of body iron stores, were at increased risk for acute myocardial infarction. During the past dozen years many studies have followed leading to intense debate on the role of iron in the development of heart disease. A meta-analysis of prospective studies found, however, no support for the iron-heart disease hypothesis. As new disease associations with iron status continue to be explored, consideration needs to be given to the lessons learned from these studies. Moreover, additional efforts need to be made to find a simple, high throughput and more satisfactory measure of the forms of iron in the body that are liable to do damage.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
