Bilibili/TikTok videos as sources of HPV-related medical information: a cross-sectional content analysis.
Article in BMC public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundFollowing the 2023 extension of HPV vaccine eligibility (9–45 years) in China, public demand for HPV-related health information has surged, with Bilibili (a long-form knowledge platform) and TikTok (a short-form high-engagement platform) emerging as core sources. This study aimed to compare uploader characteristics, content features, information quality, and the correlation between audience engagement and quality of HPV-related videos on the two platforms.
methodsOn August 8, 2025, we retrieved the top 100 videos from each platform using three search terms: “HPV vaccine”, “human papillomavirus infection”, and “cervical cancer screening”. Prior to retrieval, user accounts were logged out and browsing histories cleared to avoid personalized recommendation biases, with results displayed in the platforms’ default comprehensive ranking. After excluding irrelevant, duplicate, silent, and advertisement videos (as well as those published < 7 days), 197 valid samples were analyzed. Quality was evaluated via the Patient Education Materials Assessment Tool (PEMAT), Global Quality Score (GQS), and a customized HPV-specific checklist. Statistical analyses were performed using IBM SPSS Version 30.0, including nonparametric tests, correlation analysis, and regression models as appropriate. A two-tailed p < 0.05 was considered statistically significant.
resultsTikTok videos were significantly shorter (median: 53s vs. 278s, p < 0.01) and had higher audience engagement (median likes: 6011 vs. 420.5, p < 0.01) than Bilibili videos. Bilibili outperformed TikTok across 11 key quality metrics (e.g., PEMAT-Total: 1.0 vs. 0.84, p < 0.01), with TikTok showing a lack of preventive information (median score = 0) and 32% of non-professional uploaders’ videos on Bilibili failing to clarify HPV 16/18-cervical cancer associations. Audience engagement was positively correlated with quality on Bilibili (r = 0.25–0.31, p < 0.05) but not on TikTok. No significant quality differences were observed between professional and non-professional uploaders on either platform (all p > 0.05).
conclusionTikTok serves as an effective channel for introductory HPV science communication, while Bilibili is better suited for systematic knowledge acquisition. To enhance public health impact, platforms, creators, and regulators should collaborate: TikTok should establish quality thresholds for short-form health content, and Bilibili should further enhance the depth of professional HPV content.
