1 · What the graph read from 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.

2 · The registry

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: Trauma-related mortality remains a global concern, causing ~ 5 million deaths annually. Helicopter emergency medical services (HEMS) enable rapid transport to difficult-to-reach areas, potentially benefiting critical trauma patients. However, the survival advantage of HEMS over ground emergency medical services (GEMS) remains unclear. This systematic review evaluates the impact of HEMS versus GEMS on in-hospital trauma mortality. Methods: A literature search (2014-2024) identified studies reporting trauma patient survival and emergency medical service (EMS) transport modality. Inclusion/exclusion screening used Rayyan and multiple reviewers. Secondary inter-facility and nontrauma transports were excluded. The primary outcome was in-hospital mortality, with additional analyses of injury severity score (ISS), Glasgow Coma Scale (GCS), and regional differences. Analysis was done using an inverse variance weighting method. Results: Of 628 articles, 29 were included, covering 3,101,673 patients (602,068 HEMS, 3,158,152 GEMS). HEMS was linked to higher in-hospital mortality (odds ratio [OR] = 1.27; 95% confidence interval, 1.05-1.53; Conclusion: Despite its advantages, HEMS was associated with higher trauma mortality, suggesting selective use based on patient and regional factors. Further research should refine transport criteria.
