Abstract

fetched live from OpenAlex

Background: Three liters of polyethylene glycol administered in a split dose is a commonly recommended regimen for bowel preparation before colonoscopy. Objectives: The aim of this study was to compare the quality and tolerability of low-dose (2 L) polyethylene glycol combined with linaclotide (2 L+L) versus the 3 L polyethylene glycol (PEG) bowel preparation regimen. Design: A noninferiority, prospective, multicenter, randomized controlled trial. Methods: In this noninferiority, prospective, multicenter, randomized controlled study, patients scheduled for colonoscopy were enrolled and randomized to receive a 3 L PEG or 2L PEG+L regimen. The quality of bowel preparation and patients’ discomfort was assessed. Results: Over 12 months, 458 patients were randomized into 3 L PEG and 2 L+L groups. The primary endpoints showed that the 2 L+L regimen was superior to the 3L PEG regimen in overall bowel cleansing scores (Ottawa Bowel Preparation Scale: 3.3 ± 2.1 vs 3.7 ± 2.1, p = 0.021), but no significant difference in adequate bowel preparation rate between the two groups according to the OBPS score (97% vs 97.4%, p = 0.791). Before colonoscopy, patients in the 2 L +L regimen group had lower bloating scores (0.5 (0, 2) vs 1 (0, 3), p = 0.013), discomfort scores (1 (0, 2) vs 1 (0, 3), p = 0.006), and intolerability scores (1 (0, 3) vs 2 (0, 4), p = 0.016) than did those in the 3L PEG group. Conclusion: Two liters of polyethylene glycol combined with linaclotide may be an alternative regimen to 3 L of PEG taken in split doses for bowel preparation before colonoscopy.

Teacher imitation

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.
