Trabecular bone score as an assessment tool to identify the risk of vertebral fractures in SAPHO syndrome.

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
This is the first study to report that TBS seems not only unaffected by bone artifacts, but also is superior to BMD in the discrimination of vertebral fractures in SAPHO patients, which highlights the importance of adding TBS measurement to DXA images in routine clinical evaluation. PURPOSE: To investigate the impact of bone artifacts on trabecular bone score (TBS) and lumbar spine (LS) bone mineral density (BMD) measured by dual-energy X-ray absorptiometry (DXA) and analyze the clinical utility of TBS evaluation for vertebral fracture (VF) risk assessment in SAPHO patients compared with BMD assessment.
methodsSeventy SAPHO patients (mean age 50.1 (10.7) years, 81% women) and an equal number of age- and sex-matched controls were enrolled. TBS and BMD were assessed using DXA. Bone artifacts and VF of the spine were evaluated using whole-spine CT. Univariate logistic regression analysis was performed to identify factors associated with VF. Odds ratios (ORs) per standard deviation decrease in TBS and BMDs were estimated from logistic regression models with adjustment for age.
resultsIn patients with bone artifacts, TBS, but not LS BMD, was lower than matched controls, and in those without bone artifacts, both BMDs and TBS were lower than controls. After adjustment, LS BMD was significantly lower in the SAPHO group than in controls. TBS and LS BMD (OR [95% confidence interval], 12.0 [3.6, 40.4] and 4.7 [2.0, 10.9]) showed statistically significant ORs but the others did not. For evaluating VF in SAPHO patients, TBS showed the greatest AUC in the ROC curve, with a value of 0.920 compared with 0.777, 0.690, and 0.652 for LS, FN, and TH BMD, respectively.
conclusionTBS seems not to be influenced by bone artifacts in opposition to LS BMD and has a better discriminatory value than BMD for VF in SAPHO patients.
