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
Computed tomographic (CT) coronary artery angiography with calcium scoring is crucial in suspecting coronary artery disease (CAD). The routine protocol for CAD radiological investigation involves a precontrast series for calcium scoring and a postcontrast series for investigating structural changes in coronary arteries. This review intends to investigate the feasibility of virtual noncontrast images to replace the true noncontrast (TNC) images in coronary artery calcium scoring to decrease the radiation dose. The current review included articles found in the PubMed database. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for the further evaluation of the articles for inclusion criteria, 25 articles were finally shortlisted for the final review. It is found that the calcium score of coronary arteries estimated by virtual unenhanced images generated by dual-energy CT (DECT) is comparable with that of TNC images. The virtual unehncanced images has the potential to eliminate the need for the TNC series acquisition, thereby reducing the radiation dose. Especially, photon-counting detector-based DECT has excellent potential in the estimation of calcium scores and the reduction in radiation dose. In addition, contrast dose also can be significantly reduced, which is crucial in patients with renal insufficiency. In conclusion, using DECT for CAD investigations significantly reduces both radiation and contrast doses compared to conventional CT scans. This reduction is particularly crucial for patients who require repeated follow-up scans, as it enhances their safety and minimizes potential risks.
