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

Recent advances in CT technology have led to the advent of the photon-counting detector CT (PCD-CT). The technology has shown significant improvements in CT image quality with high spatial resolution, more accurate differentiation of coronary plaque components, and radiation reductions compared to the energy-integrating detector-CT (EID-CT). However, limited experience exists, and little has been published on the decision-making process for PCD-CT coronary scanning protocols and parameters in clinical practice. In this pictorial review, we showcase our experience in the use of PCD-CT coronary CT angiogram through a step-by-step guide in the form of a decision tree, a series of clinical cases, and a detailed discussion of each scanning protocol to aid the operator in making decisions in commonly encountered clinical scenarios. The guide should also help the operator in setting up a PCD-CT cardiac imaging service.
