Clinical study on basal blood perfusion in the major arteries of the limbs.
Article in Frontiers in medicine, 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
Background: Investigating basal blood perfusion in the major arteries of the limbs to guide flow rate selection during Methods: Volunteers undergoing physical examinations at PLAGH Fourth Medical Center (February-December 2024) were recruited. Three hundred and four eligible participants (146 males, 158 females; aged 18-65, mean 41.68 ± 11.28) were enrolled after screening. A portable Doppler ultrasound system was utilized to assess the brachial, ulnar, radial, popliteal, dorsalis pedis, and posterior tibial arteries in the limbs. Vascular diameter, blood flow velocity, and blood perfusion volume were measured for each artery. Mean hemodynamic parameters were calculated. Analyze the linear relationship between BMI, body surface area, and arterial blood perfusion volume using a multiple linear regression model. Conduct interaction tests to investigate whether there are sex-specific or "three-high" status-specific effects in the linear prediction model of blood perfusion volume by BMI and body surface area. Results: Ultrasound findings revealed the following mean blood perfusion volumes in the upper limb arteries: brachial artery, 74.9 ± 22.5 mL/min; ulnar artery, 35.7 ± 12.6 mL/min; radial artery, 36.8 ± 13.5 mL/min. In the lower limb arteries, the mean blood perfusion volume was: popliteal artery, 114.1 ± 34.2 mL/min; dorsalis pedis artery, 53.3 ± 18.1 mL/min; posterior tibial artery, 59.2 ± 21.0 mL/min. No significant difference was observed in mean blood perfusion volume between the ulnar and radial arteries ( Conclusion: Quantitative ultrasound-derived limb perfusion parameters and their BMI/BSA correlations enable hemodynamic customization for machine perfusion systems in limb replantation. This standard approach balances metabolic support and ischemia-reperfusion risk mitigation during extracorporeal preservation, advancing personalized transplant protocols.
