Geographic and Temporal Distribution of Mortality Rates for Multiple Sclerosis in Canada, 1965–1994
Bibliographic record
Abstract
Statistics Canada data were used to calculate multiple sclerosis (MS) mortality rates per 100,000 population in the Canadian provinces from 1965 to 1994. For the period 1965-1994, the highest average annual MS mortality rates were in Quebec (4.4) and Ontario (3.9), while the Western Provinces had an intermediate rate (2.1) and the Atlantic Provinces had the lowest rate (1.2). Female mortality rates exceeded male rates in each of the four regions. Average annual MS mortality rates in Canada overall fluctuated during the past 30 years, with rates of 3.4 in 1965-1969, 4.2 in 1970-1974, 3.2 in 1975-1979, 2.3 in 1980-1984, 2.8 in 1985-1989 and 3.9 in 1990-1994. Female mortality rates exceeded male rates during each 5-year period. The highest mortality rates for both genders were in the 65 years plus age group. Rates in the under 45 years age group have remained stable, while rates in both the 45-64 and 65 years plus age groups have fluctuated. There is no apparent relationship between prevalence and mortality rates among the Canadian provinces.

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.
