1 · What the graph read from it

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.

2 · The registry

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

backgroundChronic constipation is common, and the appropriate use of stimulant laxatives remains challenging. Although dependence due to habitual stimulant-laxative use is frequently observed, the long-term effects of regular use on dependence and tolerance have not been fully elucidated. This study aimed to characterize the clinical features and substance use-related symptoms associated with stimulant-laxative use in patients with chronic constipation.

methodsThis multicenter prospective observational study was conducted at three centers and enrolled patients with chronic constipation, including those meeting the Rome IV criteria. Patients were categorized based on stimulant-laxative use into None (N), Short-term/Rescue (SR), and Regular (R), defined as the use of stimulant laxatives ≥ 3 per week for > 1 year. Substance use-related symptoms were assessed using the CAGE-AID questionnaire (≥ 2 point), and self-reported ICD-11 and DSM-5-TR substance use disorder criteria.

resultsA total of 280 patients were included (N = 197, SR = 51, R = 32). Baseline characteristics did not differ significantly among groups. CAGE-AID positivity was 5.1%, 58.8%, and 90.6% in the N, SR, and R groups, respectively. ICD-11 criteria were markedly higher in the R group (65.6%) compared with the N (0%) and SR (11.8%) groups. DSM-5-TR criteria showed a similar pattern (0%, 15.7%, and 65.6%, respectively). The R group consistently demonstrated higher positive screening rates across all tools.

conclusionsLong-term stimulant-laxative use is associated with increased substance use-related symptoms and features suggestive of habituation in patients with chronic constipation.

trial registrationThe study was registered in the University Hospital Medical Information Network (UMIN000051617) on July 15, 2023.
