A cross-sectional assessment of the quality and reliability of sleep disorder information on Douyin (TikTok in China).
Article in Scientific reports, 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
Short-video platforms such as TikTok have become significant sources of health information, particularly among younger populations. However, the quality and reliability of health-related content on these platforms remain a concern. This investigation examines the current landscape of sleep disorder information on Douyin (TikTok in China). To evaluate the quality, trustworthiness, and thematic completeness of sleep disorder-related short videos on Douyin (TikTok in China). We conducted a cross-sectional study by retrieving the top 200 videos from Douyin using a combination of three Chinese keywords ("" [sleep disorders], "" [insomnia], and"" [sleep]). The top 200 videos from each keyword search were pooled. After removing duplicate listings, commercial advertisements, and off-topic videos, 154 videos were included in our final study. Engagement metrics-including likes, comments, favorites, and shares-were collected to quantify the influence of the short videos. The quality of these videos was evaluated using the modified DISCERN instrument, the JAMA benchmark criteria, the Global Quality Scale (GQS), and a content-specific tool designed to assess six key domains. Double-blinded assessments were performed. Most videos were created by healthcare professionals. Overall quality was moderate (median scores: GQS = 2, JAMA = 2, mDISCERN = 2). Notable content gaps were identified: 34.4% lacked information on detection, 40.3% provided minimal treatment details, and 52.6% omitted outcomes. Videos from healthcare professionals scored significantly higher (p < 0.05). Engagement metrics correlated positively with quality scores. Sleep disorder-related content on Douyin (TikTok in China) is of moderate quality, with professional sources demonstrating superior reliability, suggesting the need for greater efforts to standardize health-related content on such platforms. Strengthening content verification and encouraging professional involvement are essential.
