Medication literacy scale for patients with chronic constipation.
Article in Exploratory research in clinical and social pharmacy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Chronic constipation (CC) is a common gastrointestinal disorder. The disease-specific medication literacy (ML) of people with CC should be assessed because appropriately managing laxatives requires professional guidance, and patients must be able to understand and manage medications. The aim in this study was to develop a Medication Literacy Scale for Patients with Chronic Constipation (MLS-PCC) and evaluate the validity in accordance with the Consensus-based Standards for the selection of health measurement instruments guidelines. Methods: The MLS-PCC was developed through item generation and qualitative pilot surveys, followed by quantitative pilot surveys to evaluate content validity. An online cross-sectional survey was then administered to 423 adults with CC in Japan. The structural validity was evaluated using exploratory and confirmatory factor analyses. Between-group differences in the total and subscale scores were examined. Results: The final MLS-PCC comprised nine items within three factors-functional, interactive, and critical subscales. The fit of the model was good (CFI = 0.98, TLI = 0.96, and RMSEA = 0.058), with satisfactory reliability ( Conclusions: The content and structural validity of the MLS-PCC were high; the MLS-PCC can serve as a practical tool for assessing ML among patients with CC. The MLS-PCC may support pharmacists and other healthcare professionals in optimizing patient education, enhancing communication, and promoting safe and effective medication use.
