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

purposeThis study evaluated the relationship between image quality level (IQL), radiation dose, image noise, and signal-to-noise ratio (SNR) in pediatric head CT, comparing energy-integrating detector CT (EID-CT) and photon-counting CT (PCCT) across age-specific phantoms.

methodsHead CT scans of 1-, 5-, and 10-year-old anthropomorphic phantoms were performed across a range of IQLs on EID-CT and PCCT. For each IQL, radiation dose, image noise, and SNR were recorded and compared between the two systems.

resultsPCCT required lower CTDI

conclusionPCCT offers superior SNR for brain and bone while reducing radiation dose, with the largest radiation dose benefit in older pediatric phantoms, supporting optimized pediatric neuroimaging.
