The quality and reliability of short videos about myocardial infarction on TikTok: a cross-sectional study.
Article in Frontiers in public health, 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
Introduction: Myocardial infarction (MI) is one of the major diseases affecting human health and life, characterized by its acute onset and high mortality rate. Social media platforms like TikTok are playing an increasingly important role in disease education and prevention. This study evaluated the quality of MI-related science education videos on TikTok and examined the relationship between video content quality and user engagement. Methods: Video quality was assessed using the Global Quality Scale (GQS), Journal of the American Medical Association (JAMA) benchmark standards, and the modified DISCERN (mDISCERN) tool. Video duration and engagement metrics (likes, comments, shares, and collections) were recorded. Spearman's correlation and linear regression analyses were employed to examine the relationship between video quality and engagement. Results: After screening the videos, a total of 270 videos were analyzed. Collectively, these videos garnered 35,913,507 likes, 12,745,256 shares, 8,072,837 collections, and 1,306,276 comments. Most videos (84.1%, Discussion: As a widely used video dissemination platform, TikTok provides users with a positive experience, with the overall quality of MI-related short videos remaining at a moderate level. Analysis indicates that extending video duration and appropriately citing references and sources can further enhance video quality and reliability, offering users more comprehensive knowledge and improved disease prevention outcomes.
