The Usefulness of Physician-Staffed Helicopters for Managing Severe Abdominal Trauma Patients.
Article in Journal of emergencies, trauma, and shock. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
Introduction: We retrospectively investigated prognostic factors for severe abdominal trauma patients evacuated by a physician-staffed helicopter emergency medical service (HEMS) and ground ambulance using the Japan Trauma Data Bank (JTDB). Methods: The study period was from January 2004 to May 2019. The subjects were divided into two groups, according to the type of outcome: the Mortality group, which included patients who ultimately died, and the Survival group, which included patients who obtained a survival outcome. Results: There were 2457 in the Mortality group and 11,326 in the Survival group. When variables that showed statistical significance in the univariate analysis were included in a multivariate analysis, the following variables were identified as significant positive predictors of a fatal outcome: evacuation from the scene, blunt injury, injury severity score, and age; significant negative predictors of a fatal outcome were transportation by the HEMS and revised trauma score. Conclusions: The present study described the usefulness of the HEMS for severe abdominal trauma patients in comparison with ground ambulance transportation using the JTDB.
