Visualized analysis of research on helicopter emergency medical service.
Article in Medicine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundNumerous studies have confirmed that helicopter emergency medical services (HEMS) play a positive role in prehospital care. However, few studies have used rigorous bibliometric tools to analyze the knowledge structure and distribution of HEMS research.
objectivesThe purpose of this study was to use bibliometric methods to conduct a quantitative and qualitative analysis of the HEMS-related literature and to determine the research status and hotspots of HEMS research.
methodsCiteSpace was used for bibliometric analysis of the HEMS-related literature retrieved from the Web of Science database from 1989 to 2021.
resultsA total of 1378 HEMS-related literature were included. Collaboration among countries, authors, and institutions needs to be strengthened. The topics in HEMS research have mainly focused on the effectiveness of helicopter emergency medical services for trauma patients and the comparison of transport effectiveness between helicopters and ground emergency medical services on trauma patient transport. Research over the past 10 years has mainly focused on the application of HEMS in patients with trauma, myocardial infarction, cerebral apoplexy, application of tracheal intubation technology in HEMS, and advanced airway management. In recent years, HEMS research trends have mainly included out-of-hospital cardiac arrest, and transport.
conclusionsCiteSpace was used to visualize and analyze the HEMS-related literature, which visually reflected the research status and hot spots, providing references for the topic selection and development direction of HEMS research.
