Assessing the content and quality of deep vein thrombosis on Bilibili, TikTok, and YouTube: a cross-sectional study.
Article in Thrombosis journal, 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
backgroundDeep vein thrombosis (DVT) is a form of venous thromboembolism, occurring in approximately 1.6 out of every 1000 people annually. Social media platforms have become influential tools for disseminating health information.This study aimed to comprehensively evaluate the content, quality, and reliability of DVT-related videos on TikTok, Bilibili, and YouTube.
methodsA comprehensive search was conducted on Bilibili, TikTok (Douyin), and YouTube using three keywords - "", "Deep vein thrombosis", and "DVT" - across all platforms.Two reviewers independently assessed video characteristics, categorized content (definition, etiologies and causations, symptoms, treatment, prevention, and complications), and evaluated quality using validated tools [Global Quality Scale(GQS), The Journal of the American Medical Association (JAMA), and modified DISCERN (mDISCERN) scores].
resultsAnalyzing 300 DVT-related videos revealed distinct content distribution patterns across platforms. On TikTok, prevention (24%), etiologies and causations (23%), and symptoms (21%) predominated; on Bilibili, treatment (30%), prevention (29%), and complications (16%) were most common; while on YouTube, treatment (25%), symptoms (24%), and etiologies and causations (18%) were prioritized. Quality assessment showed moderate overall scores: median GQS of 4 (Q1-Q3: 3-4) for TikTok and YouTube, compared to 3 (Q1-Q3: 3-4) for Bilibili (p = 0.02).TikTok videos had significantly higher modified DISCERN scores (4, Q1-Q3: 3-4) compared to Bilibili (3, Q1-Q3: 3-4) and YouTube (3, Q1-Q3: 2-3) (p < 0.0001). TikTok and Bilibili videos had higher JAMA scores (2, Q1-Q3: 2-2) than YouTube (2, Q1-Q3: 1-2) (p < 0.0001).
conclusionsAlthough DVT-related videos on social media offer valuable information on prevention and treatment, content on diagnosis and epidemiology is lacking.Videos created by medical professionals showed higher quality across all assessment metrics.Efforts should focus on improving the comprehensiveness and reliability of health information on social media platforms to enhance public awareness of DVT.
