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

purposeTo evaluate the effect of a whole-heart motion correction algorithm (Snapshot freeze 2, SSF2) on image quality, calcium score, and risk category classification of non-contrast-enhanced cardiac CT. MATERIALS AND

methodsSixty-one coronary calcium scoring scans performed on a 256-row detector CT were included. Images of standard reconstruction without motion-corrected (STD) and with SSF2 were compared. The image quality was graded by consensus of two experienced radiologists using a four-point Likert scale. The diameter of the major and minor axes at the heaviest point of a dominant calcification, as well as its volume, were measured. The Agatston score, volume score, and corresponding risk category for each patient were recorded. Paired t test, Wilcoxon test, and Bland-Altman plot were used for statistical analysis.

resultsImage quality was significantly improved with SSF2 (P < 0.001). The mean diameters of the major and minor axes were 10.5 ± 5.3 mm and 6.4 ± 6.8 mm for STD images, and 7.2 ± 4.6 mm and 4.2 ± 5.5 mm for SSF2 images, resulting in a mean volume of 149.6 ± 206.1mm

conclusionMotion correction with SSF2 in non-contrast-enhanced cardiac CT improves the image quality at both the patient and lesion level, resulting in a significant reduction in calcium score and risk category downgrade.
