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

BACKGROUND/

aimDual-energy computed tomography (DECT) is an advanced imaging modality that enables material differentiation and enhanced diagnostic capabilities. This study aimed to investigate clinical DECT utilization in hospitals through a nationwide questionnaire survey. PATIENTS AND

methodsAn electronic questionnaire survey was sent to medical staff to investigate the use of DECT in clinical practice at each hospital in Japan. The questionnaire consisted of two parts: the first part asked for general information about the hospital, and the second asked for the detailed utilization of DECT in clinical practice.

resultsA total of 231 responses were analyzed, among which 176 hospitals had 252 DECT scanners. Most DECTs (92.5%) were used in CT departments, while 6%, 1.2%, and 0.4% scanners were used in emergency, radiotherapy, and angiography departments, respectively. Without a contrast-enhanced agent (CEA), the examinations using DECT were mostly performed for the spine, extremities, and head regions, whereas with CEA they were performed for the chest, abdomen, and vasculature regions. The virtual monochromatic images (VMI) were most frequently reconstructed in clinical practice for both without (69.0%) and with (88.9%) CEA, and calcium and iodine density images were the next most used in examinations without CEA (22.6%) and with CEA (50.8%), respectively. The iodine reduction using low-keV VMI was performed in a 36% DECT scanner.

conclusionThe clinical utilization of DECT, including the type of DECT scanner, department of installation, scanned objects, and reconstructed images varied considerably across hospitals.
