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
Introduction: This study investigates how multimodal metaphors convey two core Traditional Chinese Medicine (TCM) concepts- "Yin Xu" (Yin deficiency) and "Yang Xu" (Yang deficiency)-in short science communication videos on Douyin. Drawing on Conceptual Metaphor Theory, Multimodal Metaphor Theory, and Visual Grammar Theory, this research examines the effectiveness of multimodal representation of TCM concepts in digital health communication. Methods: This study adopts a quantitative multimodal discourse analysis approach to analyze 15 short videos on Yin Xu and Yang Xu published on Douyin between 2023 and 2024. Using ELAN software, 89 metaphorical units were annotated across four semiotic modes (written signs, pictorial signs, sound, and gesture) to evaluate their performance, distribution, and cross-modal coordination. Results: Findings indicate that 43.8% of metaphorical mappings exhibit source-target domain inconsistencies, accompanied by insufficient cross-modal coordination and minimal dynamic narrative elements. Written text overwhelmingly dominates the modal distribution at 67.4%, while visual elements remain notably underrepresented at 21.3%. These findings suggest that multimodal inconsistency and visual underutilization may compromise the conceptual coherence of TCM metaphorical communication. Discussion: In response to these identified shortcomings, this paper presents optimization strategies focused on color-based coding systems, dynamic narrative construction, and enhanced cross-modal integration. By developing a systematic framework for enhancing the precision and coherence of TCM metaphor representation in digital media, this research contributes to the convergence of semiotic analysis, science communication, and cognitive linguistics.
