Association between deltoid muscle attenuation and sedation requirement in anterior shoulder dislocation.
Article in BMC musculoskeletal disorders, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundObjective radiological predictors of sedation requirement during closed reduction of anterior shoulder dislocation have not been clearly established. This study aimed to evaluate the association between humeral head displacement parameters and computed tomography (CT)-based deltoid muscle morphology and attenuation with sedation requirement.
methodsA total of 467 patients presenting with anterior shoulder dislocation between May 2020 and February 2026 were retrospectively screened, and 213 patients were included after applying exclusion criteria. Closed reduction was performed without sedation in 182 patients and under procedural sedation in 31 patients. Humeral head displacement length, humeral head area, and the displacement length-to-head area index (HNADI) were measured on anteroposterior radiographs. CT measurements included anterior, lateral, and posterior deltoid muscle thicknesses, total cross-sectional area, and deltoid muscle attenuation (Hounsfield Units, HU). Independent predictors of sedation requirement were analyzed using multivariate logistic regression.
resultsPatients requiring sedation were significantly older (p=0.022), and age remained an independent predictor in multivariate analysis (OR=1.052, p=0.003). Deltoid HU was significantly higher in the sedation group (p<0.001) and independently associated with sedation requirement (OR=1.133, p<0.001). Humeral head displacement length, humeral head area, HNADI, and deltoid muscle morphometric parameters were not independently associated with sedation requirement.
conclusionSedation requirement during closed reduction of anterior shoulder dislocation is associated with advanced age and increased deltoid HU rather than bony displacement parameters. CT-based assessment of deltoid HU may have potential as an adjunctive parameter for pre-procedural sedation planning.
