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
Background: There is insufficient evidence on the relationship between psychological distress and patients with non-obstructive coronary artery disease (NOCAD) who experience angina symptoms despite having non-significant narrowing or normal coronary arteries. Therefore, our aim is to evaluate the psychological distress status in patients with NOCAD. Materials and Methods: In this prospective cross-sectional study, patients with symptomatic angina scheduled for coronary angiography were screened and invited to participate, alongside a control group of non-symptomatic individuals. Symptomatic patients were categorized as having obstructive (OCAD) or NOCAD based on angiogram results. All participants completed the Hospital Anxiety and Depression Scale (HADS) to assess their psychological state and provided blood samples for stress biomarker analysis. Results: A total of 124 subjects participated in this study. The prevalence of anxiety and depression (HADS score ≥8) in patients with OCAD and NOCAD were 26.2% and 25%, respectively. The HADS anxiety (HADS-A) score was higher in both OCAD ( Conclusion: Higher anxiety scores indicate significant emotional distress in patients with NOCAD. Furthermore, anxiety shows a notable association with NOCAD in patients presenting with angina.
