Mortality and Cancer Experience of Quebec Aluminum Reduction Plant Workers. Part 3: Monitoring the Mortality of Workers First Employed After January 1, 1950
Bibliographic record
Abstract
OBJECTIVE: To monitor changes over time in mortality of workers first employed in Quebec aluminum smelters after January 1, 1950 (1951-one cohort). METHODS: Mortality of cohorts by decade of hire was compared with Quebec and same plant experience before 1950 (1951). RESULTS: Chronic obstructive pulmonary disease and respiratory cancer (one cohort each) mortality were statistically in excess. In the combined cohorts, standardized mortality ratios exceeded 110 for cancers of esophagus, rectum, and rectosigmoid junction, pancreas, larynx, lung, non-Hodgkin lymphoma, cerebrovascular disease, and asthma. These findings essentially mirrored the experience of pre-1950 workers. There was a significant downward trend in mortality from all causes, lung and bladder cancer. CONCLUSIONS: Statistically significant improvements were found in mortality from all causes combined, from cancer and from cancer of the lung and bladder. Slightly increased mortality continues from certain other causes.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
