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
Background: The diagnostic efficacy of the magnetic resonance imaging (MRI)-based vertebral bone quality (VBQ) score for osteoporosis in patients undergoing lumbar surgery has been documented; however, whether the VBQ is influenced by different magnetic field strengths (1.5 T and 3.0 T) remains controversial. This study aimed to investigate the influence of magnetic fields on the diagnostic efficacy of the VBQ score via self-paired patients who underwent both 1.5 T and 3.0 T MRI scanning. Methods: This retrospective study included consecutive patients aged >50 years who underwent ≥2 MRI examinations within a 6-month period at our department for degenerative lumbar surgery from June 2022 to June 2024. Patients were included only if they had both dual-energy X-ray absorptiometry (DXA) and quantitative computed tomography (QCT) results obtained within the same period. There were three MRI scanners in our institution: the GE 1.5 T (General Electric), the GE 3.0 T (General Electric), and the PH 3.0 T (Philips Healthcare, Amsterdam, the Netherlands). The self-paired VBQ scores were compared between the different magnetic fields and scan manufacturers using paired Results: A total of 104 patients were included who underwent ≥2 MRI scans with available DXA and QCT results. The mean age was 65.3±8.8 years with 56.7% female participants. In self-paired analysis, a significantly higher VBQ score was found in 1.5 T compared with 3.0 T (3.2±0.59 Conclusions: The VBQ 1.5 T has a significantly higher cutoff value for osteoporosis than the VBQ 3.0 T in patients undergoing lumbar surgery. It is essential to mention the magnetic resonance (MR) field when applying the VBQ score in the screening of osteoporosis.
