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.
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
Purpose: Fast-field echo resembling a computed tomography using restricted echo-spacing (FRACTURE), a magnetic resonance imaging (MRI) sequence (Philips Healthcare) providing computed tomography-like bone contrast, enables excellent visualization of bones and tendons. Volume rendering (VR) images created from this sequence show anatomical details of a patient's actual structures. This study evaluated the diagnostic performance of FRACTURE and its VR images for visualizing wrist tendons on MRI images from patients and healthy individuals. Methods: Twenty subjects were included, 10 patients with tendon injuries and 10 healthy individuals who underwent MRI scanning. The imaging protocols were FRACTURE (with VR images), T2-weighted imaging (T2WI), and proton density-weighted volumetric isotropic turbo-spin-echo acquisition (PD-VISTA). An orthopedic surgeon, a hand-surgery specialist, and a radiologist not involved in the surgeries used three methods to interpret the images: FRACTURE multiplanar reconstruction, FRACTURE VR, and PD-VISTA + T2WI. The assessment criteria included tendon injury diagnostic accuracy, interpretation time, and ease-of-interpretation scoring. Diagnostic accuracy was calculated as the correct diagnosis rate. Interpretation time and scoring were analyzed by paired Results: Fast-field echo resembling a computed tomography using restricted echo-spacing VR showed the highest tendon injury diagnostic accuracy, with considerably better interpretation time performance and ease-of-interpretation scoring versus PD-VISTA + T2WI. In the surgical cases, the tendon rupture sites on FRACTURE images corresponded to the intraoperative findings. Conclusions: Fast-field echo resembling a computed tomography using restricted echo-spacing was excellent across all assessment criteria, and FRACTURE VR had particularly high diagnostic performance and clinical utility. Although obliquely oriented tendons, such as of the thumb and little finger, require consideration of the magic angle effect, clear visualization of these tendons was possible with appropriate positioning. Additionally, FRACTURE's high tendon visualization capability enabled the identification of anatomical variations, enhancing its usefulness in clinical hand-surgery practice. Clinical relevance: Tendon injury diagnosis was faster and more accurate with FRACTURE VR than with conventional sequences.
