SEX HORMONE LEVELS IN SERUM IN RELATION TO THE DEVELOPMENT OF BREAST CANCER
Abstract
In 1974, approximately 13,000 female residents of Washington County, Maryland, donated 15 ml of blood as part of a project to determine if certain serologic factors were related to the development of site-specific cancer. Sera were stored at -73 C. The present study reports the associations of serum levels of estrone, estradiol, estriol, androstenedione, progesterone, and testosterone with breast cancer among 17 premenopausal cases diagnosed 8-132 months after blood was drawn, and 39 postmenopausal cases diagnosed 6-72 months after blood was drawn. Each case was matched to four controls selected from the other serum bank donors. Matching factors were age, race, and time since last menstrual period. Cases and controls who were taking estrogen-containing preparations were excluded from this analysis. Sera were analyzed without knowledge of case-control status. Differences in levels of serum hormones between cases and controls were slight and not statistically significant.

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.
