Article in BMC oral health, 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
aimThis study aims to assess the reliability and overall quality of publicly accessible video content related to orthognathic surgery on two major social media platforms: TikTok™ and YouTube™.
methodA total of 320 videos were systematically analyzed on TikTok™ and YouTube™ using the search terms “jaw surgery” and “orthognathic surgery.” Data collection was carried out between March and April 2024. Each video was evaluated using the Global Quality Score (GQS) to determine general content quality and a modified version of the DISCERN instrument to assess reliability. Video reliability was assessed using the DISCERN instrument, a standardized tool for evaluating the quality of health information. Additional parameters, including video duration, view count, number of likes, comments, and uploader type were recorded and analyzed. All searches were performed in incognito mode without VPN to minimize algorithmic bias and ensure reproducibility.
resultsFor the ‘jaw surgery’ term, statistically significant associations were observed between uploader type and platform (p < 0.05): patients were the predominant uploaders on TikTok, whereas doctors and clinics were more common on YouTube. Comparative analyses demonstrated that GQS and DISCERN scores were comparable between platforms, with TikTok showing slightly higher mean scores for the ‘Orthognathic Surgery’ term, though these differences were not statistically significant (p > 0.05). YouTube videos were longer in duration for certain comparisons, whereas TikTok videos received significantly higher engagement metrics (views, likes, comments, and subscriber counts) (p < 0.05).
conclusionThe content about orthognathic surgery on both platforms was found to be of poor to moderate quality (mean GQS: 1.40–2.49 out of 5) and limited reliability (mean DISCERN: 0.81–2.21 out of 4), with significant variation between search terms and platforms. CLINICAL TRIAL NUMBER: This study did not involve human participants, identifiable personal data, or experimental interventions. All analyzed material consisted of publicly accessible online videos, which are exempt from institutional review board approval according to relevant guideline (e.g., the Declaration of Helsinki and local regulations). Therefore, ethical approval was not required and was not sought.
