Ulcerative colitis in the county of Uppsala 1945–2007
Bibliographic record
Abstract
OBJECTIVE: The incidence of ulcerative colitis has increased in many parts of the world during the second part of the twentieth century. In the county of Uppsala in the middle part of Sweden, the epidemiology of ulcerative colitis has been studied during two different time periods, 1945-1964 and 1965-1983. These figures have now been compared to the present day situation, 2005-2007. METHOD: The incidence figures in the two first studies were the results of retrospective studies but the figures from 2005 to 2007 were generated prospectively. The clinical characteristics during 1945-1964 were described according to the Montreal classification and a comparison between the first and third study periods could therefore be done. RESULTS: During the study period, the population of the county increased from 146000 to 323270 inhabitants. The crude incidence of ulcerative colitis increased from 2 to 19.2 new cases per 100000 inhabitants/year. The age distribution was remarkably stable when the first 20 years was compared with the last 3 years (mean age 36 vs. 38.1 and range 2-84 vs. 3-84) except for those below 11 years of age. CONCLUSION: Between 1945 and 2007 the incidence of UC in the County of Uppsala increased from 2 to 19.2 new cases/100000. The increase affected all age groups except those below 11 years of age.

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.
