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

backgroundDual energy CT (DECT) has been demonstrated to improve relative stopping power (RSP) estimation with knowledge of the effective atomic number ( PURPOSE: This study evaluates the accuracy of a fast kV switching DECT to calculate

methodsFive different phantoms containing tissue-mimicking inserts were scanned using the Body Scanning Field of View (SFOV) of a fast kV switching DECT. Head phantoms were rescanned with the Head SFOV. Data from the DECT was used to obtain voxel-matched

resultsThe largest differences were seen in the low-density inserts. The mean absolute percent error (MAPE) of

conclusionsUltra-fast kV switching DECT can be used to predict RSP in phantom with an accuracy that is non-inferior to the range uncertainties commonly used in the clinical environment and has the potential to be used for proton therapy planning.
