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

objectiveWe evaluated ex vivo feasibility of ice-ball visualization during bone cryoablation using dual-energy computed tomography (DECT). MATERIALS AND

methodsThis ex vivo study included three porcine cadavers on which cryoablation was performed on four vertebrae. Spectral DECT acquisitions were made at 0 and 10 min after ablation. Conventional images, virtual monoenergetic images (VMIs) at 50 keV, electron density (ED), effective atomic number (Z

resultsFor each pig, the ice-ball was visible in soft tissues on all spectral images except on Z

conclusionThe fusion of spectral ED and VNCa images could show potential in improving the visualization of the ice-ball during bone cryoablation. RELEVANCE STATEMENT: Fusion of electron density and virtual non-calcium images enhances the ice-ball visualization in bone during spinal cryoablation. KEY POINTS: The lack of visibility of the ice-ball in the bone during cryoablation represents a limitation for the safety of adjacent structures at risk. In bone, the ice-ball was detectable only on virtual non-calcium (VNCa) images, but the quality of its contour delineation was poorer. Electron density and VNCa fusion images improved ice-ball visualization and delineation in bone, as confirmed by comparison with MRI.
