Abstract
<h3>Background</h3> Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is one of the most feared complications of ERCP. Much attention has been given on the pharmacologic prevention of this serious adverse event. Evidence suggests that statins may exhibit anti-inflammatory properties in the pancreas, but studies have conflicting results on its role on the prevention of PEP. This study aims to investigate whether the use of statins has a protective effect against PEP. <h3>Methods</h3> A comprehensive, computerized literature search from the PubMed Central, Embase, Cochrane Library, and OVID was performed with the following search terms: statins, lipid-lowering drugs, post-ERCP pancreatitis, pancreatitis, PEP, and prevention. Four cohort studies were selected and validated using the Newcastle-Ottawa criteria. Trial results were combined under a random effects model. The Cochrane Review Manager Software version 5.3 was used for all analyses. <h3>Results</h3> Four cohort studies comprising of 5832 patients were analyzed. In the random effects model, the pooled odds ratio (OR) of PEP occurrence was 0.73; 95% CI (0.36–1.45). The pooled data of the four studies showed a trend towards a beneficial effect of statin use and decreasing risk of PEP but did not show a protective effect of the statin. Likewise, there was a substantial degree of heterogeneity (I<sup>2</sup>=87%). Subgroup analysis was done, which include two studies on chronic statin use defined as use for more than six months. It showed a pooled OR of PEP recurrence of 0.41; 95% CI (0.30–0.57) using the random effects model, thereby signifying a protective effect of the drug. The subgroup analysis has also resulted to a statistical homogeneity of the trials (I<sup>2</sup> = 0%). <h3>Conclusions</h3> Chronic statin use for more than six months has a protective effect against PEP. This meta-analysis has shown the potential role of statins as prophylactic agents for PEP. However, further prospective randomized studies are recommended to confirm this relationship.

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
