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 aims to investigate the knowledge and attitude of medical staff towards 3D Black Blood MR Angio methods in high-resolution magnetic resonance vessel wall imaging (HR-MRI) of intracranial arteries. Methods: A cross-sectional study conducted from August 2-25 2024 collected demographic information, knowledge, and attitude scores of medical staff through self-designed questionnaires. The questionnaires exhibited a high internal consistency (Cronbach's α = 0.870). The Questionnaire Star online platform was used, and a WeChat-based applet generated a QR code for participants to access and complete the questionnaire. Results: A total of 287 valid questionnaires were enrolled. The median (25% quartile and 75% quartile) of knowledge and attitude scores were 12 (9, 15) (possible range: 0-17) and 59 (55, 64) (possible range: 18-90). The correlation analysis demonstrated a positive correlation between knowledge and attitude (r = 0.361, P < 0.001). Multivariate logistic regression analysis showed that holding an intermediate title (OR = 4.065, 95% CI: 1.529, 10.808, P = 0.005), a vice senior title (OR = 5.443, 95% CI: 1.614, 18.361, P = 0.006), and having no prior experience with HR-MRI (OR = 0.422, 95% CI: 0.236, 0.753, P = 0.003) were independently associated with knowledge. Having one year or less of work experience (OR = 0.095, 95% CI: 0.010, 0.952, P = 0.045), having 1-3 years of work experience (OR = 0.330, 95% CI: 0.114,0.957, P = 0.041), and having no prior experience with HR-MRI (OR = 0.422, 95% CI: 0.236,0.753, P < 0.001) were independently associated with attitude. Conclusion: This study identified suboptimal knowledge and inconsistent attitudes toward intracranial HR-MRI among medical staff, with professional title, scanning experience, and prior HR-MRI exposure being key determinants. Addressing these gaps through competency-based credentialing and standardized protocol dissemination is critical to realizing HR-MRI's clinical potential in cerebrovascular care.
