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
backgroundThis study aimed to develop a machine-learning model using self-report questionnaires to screen for clinically significant anxiety symptoms in patients with breast cancer experiencing severe distress.
methodsA cohort of 327 breast cancer clinic patients was included. Anxiety symptoms were evaluated using the State-Trait Anxiety Inventory-State (STAI-S), State-Trait Anxiety Inventory-Trait (STAI-T), Beck Anxiety Inventory (BAI), and Hospital Anxiety and Depression Scale (HADS) questionnaires. The high-risk anxiety group was determined based on the Mini International Neuropsychiatric Interview Patient Health Survey. Supervised machine learning models were analyzed and validated using MATLAB2022.
resultsThe BAI showed an area under the curve (AUC) of 0.782 with the logistic regression classifier. The HADS showed an AUC of 0.784 with linear discriminant analysis. STAI-S and STAI-T exhibited AUCs of 0.770 and 0.791, respectively, using Support Vector Machine with a linear kernel. Models combining multiple questionnaires yielded higher AUCs: STAI-S and STAI-T combined resulted in 0.807, STAI-S and BAI in 0.794, STAI-T and BAI in 0.808, and the combination of STAI-S, STAI-T, and BAI achieved 0.810.
conclusionThe combination models demonstrated superior performance in detecting anxiety among patients with breast cancer compared to individual questionnaires. Combining multiple self-report scales enhances screening accuracy, indicating future research should optimize these models further through integration with other methodologies.
