Pictogram comprehension and medication-use literacy among undergraduate students: a cross-sectional survey study.
Article in Journal of pharmaceutical policy and practice, 2025. 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: Pictograms are widely used in pharmacy practice to enhance patient understanding, especially in contexts where language or health literacy barriers exist. However, limited data are available on the comprehension of United States Pharmacopeia Convention: Drug Information for the Health Care Professional (USP-DI) pictograms among Thai undergraduate students. This study assessed the understanding of USP-DI pictograms and medication-use literacy, and explored factors associated with pictogram comprehension. Methods: A cross-sectional survey using a structured questionnaire was conducted among 637 university students between August 2023 and April 2024. The Medication Use Literacy Test (MULT) assessed literacy, and the USP-DI pictogram comprehension test evaluated visual understanding. Binary logistic regression was used to identify factors associated with comprehension levels. Results: Among the 637 participants, the MULT revealed high literacy, with over 90% of questions answered correctly. The mean score for USP-DI pictogram comprehension was 21.82 ± 3.82. Students in health sciences programmes demonstrated the highest proficiency in both tests, followed by those in social sciences and science and technology programmes, with statistically significant differences ( Conclusions: This study highlights disparities in pictogram comprehension among Thai undergraduates and affirms the influence of academic discipline, age, and academic performance. The findings support the need for targeted educational strategies to enhance medication-use literacy and pictogram understanding.
