Article in Frontiers in psychology, 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
Objective: This study analyzes differences in depression-related expressions between healthcare professionals and non-healthcare individuals on Chinese social media. Background: Sentiment plays a critical role in depression management, influencing condition assessment, social support, and treatment adherence. However, traditional research methods are limited by self-report bias, small samples, and constrained expression. Social media offers a unique platform to capture authentic emotions at scale. Methods: A total of 120,895 comments were retrieved from Zhihu, Weibo, and Xiaohongshu. Data underwent cleaning, relevance verification, and anonymization. Users were classified into healthcare professionals and non-healthcare individuals through profile verification and manual annotation. Sentiment analysis applied the Dalian University of Technology Sentiment Lexicon, adapted to Chinese contexts and grounded in Ekman's emotional framework (anger, disgust, fear, sadness, surprise, positive emotion). Polarity and intensity (-1 to 1) were quantified. Content analysis employed a K-Means clustering algorithm to identify thematic patterns. Content analysis was conducted using computational text analysis methods, including sentiment analysis and K-means clustering, to identify emotional and thematic patterns in depression-related social media discourse. Results: Non-healthcare individuals expressed a wider emotional spectrum (anger, disgust, fear, sadness, surprise, and positive emotions), while healthcare professionals primarily expressed anger, fear, and positive emotions. Non-healthcare discourse focused on illness experiences, stigma, and treatment conflict, whereas healthcare professionals emphasized occupational stress, emotional labor, and professional fulfillment. Conclusions: The results highlight divergent emotional orientations: patients and the public center on illness experiences, while professionals emphasize identity and occupational strain. These differences underscore the need for tailored communication strategies, empathy training, and institutional psychological support for healthcare providers.
