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

Computed tomography (CT) is a simple and useful method for monitoring during cryoablation; however, image quality is degraded by artifacts caused by the cryoprobe used during treatment. We evaluated the effectiveness of combining tilt scanning and single-energy metal artifact reduction (SEMAR) to improve image quality. A cryoprobe was inserted into an agar phantom, and CT scans were performed at various angles (0°, 5°, 10°, 15°, and 20°) with and without metal artifact reduction. The relative artifact index, calculated using the CT value standard deviation, was used to evaluate the intensity. The strongest tip artifacts occurred at 0°. The relative artifact index decreased with increasing tilt angles. The tilted scanning reduced artifacts extending beyond the cryoprobe tip, but SEMAR demonstrated a limited effect on artifact reduction. The tilted scanning method may be a useful approach for improving the image quality around the cryoprobe without increasing the exposure dose.
