Association between the chronic use of gastric acid suppressants and high-risk colorectal polyps.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND AND
aimAlthough gastric acid suppressants such as proton pump inhibitors (PPIs) and histamine-2 receptor antagonists (H2RAs) are considered safe, the consequences of hypochlorhydria and hypergastrinemia caused by chronic use are unclear. This study aimed to investigate the association between the chronic use of gastric acid suppressants and high-risk colorectal polyps, focusing on polyp size.
methodsA population-based, nested case-control study was conducted using data from the Japanese Diagnosis Procedure Combination database between 2014 and 2019. Cumulative PPI or H2RA use prior to polypectomy was evaluated during the study period. Endoscopic polypectomy was categorized as polypectomy <2 cm, polypectomy ≥2 cm, and endoscopic submucosal dissection. Baseline characteristics were compared between the high-risk (≥2 cm polyps or polyps treated by endoscopic submucosal dissection) and low-risk (<2 cm polyps) endoscopic polypectomy groups. We calculated adjusted odds ratios (ORs) using multivariable logistic regression analysis.
resultsOf 27 694 patients who underwent endoscopic polypectomy, 2518 were treated with PPIs or H2RAs for >1 year prior to polypectomy. After adjusting for age, gender, and other confounders, a higher prevalence of high-risk colorectal polyps was noted with PPI (OR: 2.67; 95% confidence interval: 2.37-3.01) and H2RA (OR: 1.86; 95% confidence interval: 1.52-2.26) use. Longer PPI or H2RA use was associated with increased risks of high-risk colorectal polyps (
conclusionChronic use of PPIs and H2RAs may be associated with high-risk colorectal polyps. Requirements for long-term gastric acid suppressant use should be reevaluated.
