Abstract

fetched live from OpenAlex

The carcinogenic effect of cigarette smoke on developing breast tissue has been shown in a study in which the risk of breast cancer was 1.69 times higher, compared with age matched controls, in women who had ever been pregnant and who started to smoke within five years of menarche. Women who had never been pregnant—and so who never achieved complete differentiation of breast cells—and who smoked heavily showed a sevenfold increased risk of breast cancer ( Lancet 2002;360:1044-9) The Canadian study investigated all women under the age of 75 years in whom breast cancer was diagnosed between …

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
