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

introductionDual-energy computed tomography (DECT) enables improved tissue characterisation and the potential to reduce contrast media dose, yet clinical practice often still uses contrast volumes comparable to single-energy CT. This study evaluates the accuracy of low-concentration iodine quantification and image quality across three DECT techniques, with specific objectives to identify the lowest reliably measurable iodine concentration and to compare normalised contrast-to-noise ratios (CNR

methodsA Multi-Energy CT Quality Assurance Phantom (CIRS Model 662) filled with iodinated contrast (Iopamiro 370 mgI/mL) at concentrations of 0.025-10 mgI/mL was scanned three times using the clinical abdominal imaging protocol at the study site, without parameter adjustment. Iodine maps and virtual monoenergetic images (VMI) were analyzed using regions of interest to evaluate iodine measurement accuracy for limit of detection (LOD) and limit of quantification (LOQ) and normalised CNR across the DECT techniques.

resultsFor VMI at 40 keV, all DECT techniques demonstrated high iodine measurement accuracy (R

conclusionsAll DECT techniques accurately quantified iodine on iodine maps. Rapid kV-switching provided the lowest LOD and LOQ, whereas the dual-layer detector offered superior image quality in terms of CNR
