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

purposeThis study aimed to evaluate the effectiveness of the Fast 3D wheel (Fast 3Dw) technique in cerebral magnetic resonance angiography (MRA) and compare it with the conventional parallel imaging (PI) technique. The primary objective was to determine whether Fast 3Dw could reduce the examination time while maintaining image quality and diagnostic accuracy in patients with cerebral aneurysms.

methodsThis retrospective study included 50 patients with unruptured cerebral aneurysms who underwent 3D time-of-flight MRA using either PI or Fast 3Dw techniques on a 3T magnetic resonance imaging scanner. The image quality was quantitatively assessed using the signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), aneurysm diameter, and vessel diameter. Qualitative image assessments included vascular clarity, artifacts, and diagnostic confidence level and were evaluated using a 5-point scale. Statistical comparisons were performed using t-tests, Wilcoxon signed-rank tests, and weighted kappa statistics.

resultsThe mean examination time for Fast 3Dw (171.5 ± 4.9 s) was significantly shorter than that for PI (383.8 ± 13.2 s; p < 0.05). Fast 3Dw exhibited a significantly higher SNR (50.0 ± 14.2) than PI (46.6 ± 12.9; p < 0.05), while CNR showed no significant difference between the two techniques. No significant differences in aneurysm diameters and vessel diameters were observed between the two methods. Qualitative evaluations demonstrated no significant differences in vascular clarity, artifacts, and diagnostic confidence levels between the two methods.

conclusionThe Fast 3Dw technique significantly reduces examination time while maintaining image quality and diagnostic accuracy in cerebral MRA compared to PI. This method may be a viable alternative for routine cerebral MRA in clinical practice.
