Abstract
AIM: To assess the effectiveness and safety of budesonide in comparison to corticosteroids, 5-aminosalicylic acid (5-ASA), or placebo for inducing remission of active Crohn's disease and for maintaining remission. STUDY SELECTION CRITERIA: Randomized controlled trials comparing budesonide to corticosteroids, 5-ASA products or placebo were included. Trials had to report on the effectiveness of treatment (defined as decreasing or maintaining Crohn's Disease Activity Index, CDAI, scores < or = 150) or adverse events. DATA ANALYSIS: After assessing the validity of study design and independent, duplicate data extraction from selected trials, summary relative risks (RR) were calculated for each outcome. A test of heterogeneity was also calculated for each outcome using a random effects model. RESULTS: Budesonide was more likely to induce remission than placebo (RR=1.82, 95% CI: 1.15-2.88) or 5-ASA (RR=1.73, 95% CI: 1.26-2.39), although only one trial compared budesonide to 5-ASA products. Although budesonide induced remission less frequently than conventional corticosteroids (RR=0.87, 95% CI: 0.76-0.995), there was no significant difference between conventional corticosteroids and budesonide for inducing remission among patients with a low disease activity (initial CDAI=200-300). Budesonide was significantly less likely to cause corticosteroid-associated adverse events than conventional corticosteroids (RR=0.65, 95% CI: 0.53-0.80). No significant difference in total adverse events or corticosteroid-associated adverse events was demonstrated between budesonide and 5-ASA or placebo. CONCLUSION: Budesonide is significantly more effective than placebo or 5-ASA for inducing remission of active Crohn's disease. Although budesonide is 13% less effective for the induction of remission in active Crohn's disease than conventional corticosteroids, it is less likely to cause corticosteroid-related adverse effects. Budesonide is ineffective in maintaining remission.

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 it
