Oral Contraceptives and Cardiovascular Disease
Abstract
Myocardial Infarction and StrokeIt is now established that in addition to increasing the risk of venous thromboembolic disease, oral contraceptives increase the risks of myocardial infarction, thrombotic stroke, and hemorrhagic stroke.11 (Some recent data suggest that oral contraceptives may also increase the risk of other forms of cardiovascular disease,17 but the findings are inconclusive and are therefore not considered in this review.) Vital statistics and epidemiologic studies in Great Britain and the United States show that among nonpregnant women of reproductive age who are not using oral contraceptives, the risks of myocardial infarction and stroke (of both categories) increase . . .

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.
