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
objectiveTo evaluate the accuracy of magnetic resonance (MR) spectroscopy in differentiating vertebral hemangiomas from spinal metastases.
backgroundMR spectroscopy (MRS) quantifies lesion composition, particularly lipid and water content. This study investigates the use of MRS-derived lipid-to-water ratios (LWRs) to distinguish typical and atypical vertebral hemangiomas (VHs) from spinal metastases.
methodsIn this IRB-approved, HIPAA-compliant prospective study, 77 vertebral regions of interest were evaluated via MRS. Lesions included typical VHs, atypical VHs, metastases, and normal bone marrow. Lipid and water spectral peaks were analyzed to calculate LWRs. ANOVA with Bonferroni correction assessed statistical significance across lesion types.
resultsMean (SD) LWRs were control 0.98 (0.59), typical VH 3.37 (2.31), atypical VH 1.34 (1.77), and metastases 1.22 (1.58). ANOVA confirmed a significant effect of lesion type on LWR (p < .001). Pairwise comparisons showed significant differences between typical VH and all other groups, while atypical VH and metastases were not significantly different.
conclusionMRS effectively differentiates typical VH from metastases and atypical VH based on LWR. The modality shows promise as a non-invasive tool in lesion characterization.
