The impact of thiopurines on surgical outcomes in inflammatory bowel disease: do they make a difference?
Bibliographic record
Abstract
Ulcerative colitis and Crohn's disease together are known as inflammatory bowel disease (IBD). Surgery is considered for more severe disease and is a dreaded consequence for patients. Thiopurines have proven efficacy in the induction and maintenance of remission of IBD, but the long-term need for surgery remains uncertain with conflicting results from the available studies. The timing and duration of thiopurines also appears to play a pivotal role in the management of these conditions and may also affect the need for surgery. Data from Denmark, Canada, Hungary and the UK appear to suggest a reduction in surgery rates prior to the introduction of anti-tumor necrosis factor (TNF) therapy. The authors aim to review the more recent literature evaluating the surgery rates in IBD and changes in disease trends over time. We ask whether increasing thiopurine prescribing has had an effect on the surgery rates in the era of biologic therapy and whether more aggressive treatment approaches have altered the natural history of IBD.

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.
