Abstract
Utilization of health care resources by obese Canadians Kostas Trakas,* ¶ MSc; Kate Lawrence, ‡ MB BS, MSc; Neil H. Shear,*†§ ¶ MD Background: The prevalence of obesity in Canada has been increasing in recent years. Using data from the National Population Health Survey (NPHS), the au-thors determined the prevalence of obesity among Canadians, the associated comorbidities and the patterns of resource utilization by obese people. Methods: The NPHS, a cross-sectional survey conducted in 1994, was adminis-tered to 17 626 Canadians 12 years of age or older who were not long-term res-idents of hospitals or long-term care facilities and were not residing on First Na-tions reserves or Canadian Armed Forces bases, or in the Yukon and Northwest Territories. For the authors ’ analysis, the study population consisted of 12 318 Canadians aged 20–64 years who were not pregnant and for whom the body

Direct model labels (unvalidated)
Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
