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: Preoperative anxiety is a common and clinically significant psychological condition among surgical patients, and illness uncertainty is considered an important psychological stressor for preoperative anxiety. Mental health literacy is an intervenable psychological resource, and its role in preoperative anxiety remains underexplored. This study aims to investigate the relationship between illness uncertainty and preoperative anxiety in surgical patients and further examine the moderating role of mental health literacy in this relationship. Methods: A cross-sectional study design was adopted. From August to October 2025, 342 surgical patients were conveniently sampled from a tertiary hospital in central China. The Mishel Illness Uncertainty Scale (MUIS), State-Trait Anxiety Inventory-State subscale (STAI-S), and the Short Version of the Mental Health Literacy Questionnaire for Adults (MHLq-SVa) were used for assessment. Descriptive statistics, univariate analysis, and Pearson correlation analysis were conducted. Multivariate linear regression and moderation analysis were used to test the potential moderating effects of mental health literacy in the relationship between illness uncertainty and preoperative anxiety. Results: Illness uncertainty was significantly positively correlated with preoperative anxiety ( Conclusion: Mental health literacy plays a moderating role in the relationship between illness uncertainty and preoperative anxiety in surgical patients. Higher levels of mental health literacy are associated with a weaker association between illness uncertainty and preoperative anxiety, while lower levels are associated with a stronger association.
