Abstract

fetched live from OpenAlex

Purpose: Despite extensive use over many decades, regimens of steroids vary between clinicians. There is a lack of clarity of initial dosing, tapering pattern and duration of steroid treatment. Although most clinicians use once a day dosing, split dosing has been studied (Powell-Tuck 1987). Thus there is a need to clearly establish an evidence-based use of corticosteroids not only to maximise benefit but also reduce serious complications. In order to define its role further a Cochrane review will be undertaken. Methods: We included randomized controlled trials (RCTs) comparing oral corticosteroids versus placebo, administered to patients with confirmed ulcerative colitis. We searched 4 electronic databases and examined multiple sources of grey literature for eligible trials. Two independent investigators assessed trial eligibility and abstracted data. For each RCT we calculated the relative risk (RR) for each outcome and used a random effects model to pool the RRs. Results: Our search identified 9 citations that met our eligibility criteria. There were significantly greater rates of clinical (9 trials; 927 patients; RR 2.27; 95% CI 1.52-3.39; p=0.0001) and endoscopic (7 trials; 436 patients; RR 2.47; 95% CI 1.50-4.04; p=0.0003) remission with corticosteroids. Notably there was no significance increase in the occurrence of adverse events (3 trials, 218 patients; RR 2.74; 95% CI 0.31-23.85; p=0.36) and the withdrawal of patients due to adverse events (5 trials; 377 patients; RR 0.60; 95% CI 0.14-2.55; p=0.49). Conclusion: Our meta-analysis showed a significantly higher rates of clinical and endoscopic remission. There was no significant increase in the occurrence of adverse events and the withdrawal of patients secondary to adverse events.

Not 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.
