Value of multimodal ultrasound in the assessment of snakebite.
Article in BMC medical imaging, 2025. 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
backgroundThis study aimed to analyze the ultrasound features of snakebite-affected limbs and explore the diagnostic utility of multimodal ultrasound.
methodsAn analysis was conducted on 70 patients with snakebites admitted to The Affiliated Hospital of Southwest Medical University from July 2023 to October 2023. Two-dimensional ultrasound was used to observe subcutaneous tissue edema, color Doppler flow imaging to observe hemodynamic changes, and shear-wave elastography to measure subcutaneous tissue elasticity. Patient demographics and multimodal ultrasound findings were recorded, comparing affected versus unaffected limbs.
resultsIn all patients, the thickness of the subcutaneous fat layer, ultrasound grayscale median value, elasticity, and limb circumferences were significantly higher on the affected side than those on the unaffected side (P < 0.05). Continuous testing was conducted on 39 patients hospitalized for ≥ 3 days, and a gradual decrease in the thickness and elasticity of the subcutaneous fat layer was observed with treatment progression.
conclusionMultimodal ultrasound can assess limb edema and provides useful indicators for assessing the risk of compartment syndrome. This provides clinicians with a decision-making reference for treatment after snakebite.
