The quality and reliability of acne-related information on Douyin and Bilibili: A cross-sectional study.
Article in Medicine, 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
Acne is a highly prevalent chronic inflammatory skin disease that significantly impacts patients' physical and mental health. This study aimed to evaluate the content, quality, and reliability of acne-related videos on Douyin (the Chinese version of TikTok) and Bilibili. Videos were searched on Douyin and Bilibili using the keyword "acne" on January 1, 2026. Video characteristics, including video duration, engagement metrics, uploader identity, and content, were collected. Video quality and reliability were assessed using the Global Quality Scale (GQS) and the modified DISCERN instrument (mDISCERN). The Mann-Whitney U test and Kruskal-Wallis test were used for subgroup comparisons, and Spearman rank correlation was used for correlation analysis. A total of 262 videos were included in this study. Video content predominantly focused on treatment (41.85% of 325 content category entries), with limited coverage of etiology (16.00%) and prevention (6.76%).The median GQS score for the overall videos was 2.00 (interquartile range: 1.00-3.00), and the median mDISCERN score was 2.00 (interquartile range: 1.00-2.00). The GQS and mDISCERN scores for Douyin videos were significantly higher than those for Bilibili (P < .05). Videos uploaded by specialized healthcare personnel had the highest GQS and mDISCERN scores (P < .05). Likes, collections, and comments were not significantly correlated with mDISCERN scores (P > .05). The quality and reliability of acne-related videos on Douyin and Bilibili were generally suboptimal, with specialized healthcare personnel-uploaded videos achieving the highest quality and reliability scores. Engagement metrics were not significantly associated with video reliability. Platform operators should strengthen content governance, encourage greater participation of qualified healthcare providers, and optimize dissemination strategies to promote high-quality, evidence-based acne information.
