1 · What the graph read from it

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.

2 · The registry

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

Photon counting detector CT (PCD-CT) is a recent advance in CT technology that offers several advantages in cardiac imaging, including ultra-high resolution (UHR), improved spectral imaging, increased iodine signal, decreased noise and artifacts, and improved radiation dose efficiency. UHR in PCD-CT improves assessment of coronary artery stenosis, stents and plaque. Spectral imaging allows lower dosage of iodinated contrast, decreases several artifacts and characterizes materials, which can be useful for removing calcific plaques, computing virtual calcium score from CTA, characterizing lesions and evaluating myocardial perfusion, late iodine enhancement and quantifying extracellular volume. In this article, we review the current clinical evidence for benefits rendered by PCD-CT in cardiac imaging, highlight key challenges and discuss prospects.
