MRI of wrist ligament trauma was similar at 7 T and 3 T with arthroscopy as a reference standard.

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
objectivesThe aim was to compare the diagnostic accuracy of magnetic resonance imaging (MRI) at 7 Tesla (T) and 3 T in patients with clinically suspected injury of the triangular fibrocartilage complex (TFCC) or the scapholunate ligament (SLL) using wrist arthroscopy as a reference standard.
methodsTwenty-four patients scheduled for wrist arthroscopy due to suspected TFCC or SLL injury were examined with 7-T and 3-T MRI before arthroscopy. Four musculoskeletal radiologists independently evaluated the MR examinations in randomized order, and the findings were compared to those at wrist arthroscopy.
resultsSensitivity, specificity, and accuracy for TFCC injuries were 0.85, 0.68, and 0.82 for 7 T and 0.75, 0.73, and 0.77 for 3 T, respectively. For SLL injuries, the corresponding values were 0.70, 0.65, and 0.74 for 7 T and 0.69, 0.55, and 0.70 for 3 T, respectively. For both TFCC and SLL injuries, no statistically significant difference between 7 T and 3 T was found, and the confidence intervals for accuracy overlapped (0.67-0.94 vs 0.63-0.88 for TFCC injuries and 0.59-0.89 vs 0.52-0.86 for SLL injuries). In 14 of 24 patients (58%), MRI contributed findings of additional types of injuries, e.g., tendon injuries and ganglia, vital for a complete diagnosis.
conclusionsThe diagnostic accuracy of MRI at 7 T was similar to 3 T for detecting injury to the TFCC and the SLL. A majority of injuries were correctly diagnosed by MRI, but some injuries found using arthroscopy were missed. KEY POINTS: Question Previous studies have found that MRI cannot reliably diagnose or rule out TFCC or SLL injury, compared to the current reference standard wrist arthroscopy. Findings The diagnostic accuracy for MRI at 7 T was similar to 3 T for detecting injuries to the TFCC and the SLL. Clinical relevance Although MRI cannot replace wrist arthroscopy, it is an important complementary tool in the diagnostic workup of suspected wrist ligament injuries, with the ability to diagnose additional types of pathologies not accessible by arthroscopy.
