Analysis of the quality and reliability of benign paroxysmal positional vertigo-related short videos on TikTok and Bilibili: A cross-sectional study.
Article in Digital health. 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: Benign Paroxysmal Positional Vertigo (BPPV) is common with high recurrence. Social media platforms like TikTok and Bilibili offer health-related content, but their quality and reliability remain unclear. Objective: This study aims to evaluate the content and quality of BPPV-related videos on TikTok and Bilibili. Methods: A total of 199 BPPV-related short videos from TikTok and Bilibili were collected between September 25 and 28, 2025. Video characteristics were extracted, and quality was assessed using the Global Quality Score (GQS) and modified DISCERN scale (mDISCERN). Content accuracy was evaluated based on clinical guidelines. Non-parametric tests and Spearman correlation analysis were used to compare uploader groups and explore the relationship between engagement and video quality. Results: The videos had a median duration of 99 seconds. TikTok videos showed significantly higher interaction metrics than those on Bilibili (all Conclusion: BPPV-related short videos on TikTok and Bilibili generally have low quality, reliability, and accuracy. While professional videos are more reliable, they lack evidence-based content and omit key information. Strengthening content moderation and increasing professional involvement is crucial for improving digital health education.
