Does popularity reflect quality? A study on the reliability and quality of CAR-T videos on Chinese short-video platforms.

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: Chimeric antigen receptor T-cell (CAR-T) therapy represents a transformative advancement in cancer treatment. While public interest in CAR-T has surged, particularly through short-video platforms like TikTok and Bilibili in China, concerns remain regarding the reliability and quality of health information disseminated through such media. Objective: This study aimed to systematically evaluate the content quality, scientific integrity, and user engagement of CAR-T-related videos on Bilibili and TikTok, and to assess whether high traffic equates to high information quality. Methods: A total of 200 Chinese-language videos (100 per platform) were identified using the keyword "CAR-T." Videos were evaluated using three scoring tools: the DISCERN instrument for reliability, the Global Quality Score (GQS), and a novel CAR-T-specific checklist assessing 12 core domains. Content characteristics, source types, and engagement metrics (likes, comments, shares, and saves) were also extracted and compared across platforms and content types. Results: TikTok videos demonstrated significantly higher user engagement but poorer structure and lower DISCERN scores than Bilibili ( Conclusion: CAR-T-related content on Chinese short-video platforms is characterized by a disconnect between popularity and information quality. Effective science communication strategies and platform-level interventions are needed to mitigate misinformation risks and improve the dissemination of high-quality medical content.
