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: Cardiac power (CP; CP = 0.222 × cardiac output × mean blood pressure) output in patients with heart failure has been studied previously, but its importance in patients with hypertrophic cardiomyopathy (HCM) remains unclear. The present study aimed to explore the role of normalized CP (normalized CP = CP/ventricle mass) in assessing cardiac function in patients with HCM with normal ejection fraction using cardiac magnetic resonance (CMR). Methods: This cross-sectional study enrolled 99 patients with HCM who underwent CMR from December 2020 to January 2022 at Beijing Anzhen Hospital, and these patients were classified into heart failure or non-heart failure subgroups. Meanwhile, a control group comprising 65 gender- and age-matched healthy volunteers was also enrolled. The baseline clinical characteristics and cardiac functional parameters were compared between the patients with HCM and the controls, and multivariable linear regression analysis was performed to analyze the relationship between normalized CP and the relevant factors. Results: Significantly higher CP (1.19 Conclusions: Normalized CP decreased significantly and was negatively correlated with ventricle mass, indicating impaired cardiac pump function in patients with HCM. Normalized CP might play a critical role in detecting and evaluating impaired cardiac pump function in patients with HCM with preserved ejection fraction.
