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

backgroundThe increasing adoption of individual urban mobility in European cities is contributing to a rise in the number of bicycle and e-scooter users. Consequently, a corresponding increase in accidents, along with an additional burden on emergency departments, is anticipated, particularly in metropolitan areas. The objective of this prospective cross-sectional study was to gather detailed information regarding the patient demographics, accident mechanisms, and injury patterns of e-scooter riders in comparison to cyclists. Identifying any differences between these groups will provide a foundation for developing targeted prevention strategies and safety measures aimed at reducing the incidence of accidents and injuries.

methodsAll patients who presented to the emergency department of our level I university trauma center after an accident involving a traditional bicycle without electric assistance or an e-scooter in 2022 were recorded. Demographic data as well as information regarding the trauma mechanism, injury pattern, alcohol influence, treatment requirements and helmet use were analyzed and compared between the two groups.

resultsIn 2022, a total of 626 patients were identified after a bicycle accident and 98 patients after an e-scooter accident. E-scooter riders were with a mean age of 31.0 years (standard deviation (SD) 10.7) significantly younger compared to bicycle riders at 43.2 years (SD 16.5; p < 0.001). More than half of the patients in both groups were male (e-scooter 69.4% versus bicycle 60.7%). E-scooter riders were more likely to be intoxicated (31.6% vs. 5.4%; p < 0.001), not wearing a helmet (93.9% vs. 78.4%; p < 0.001) and to have had accidents at nighttime (39.8% vs. 11.5%; p < 0.001). There was no significant difference between the distribution of minor (e-scooter 75.2% vs. bicycle 70.3%) and major (24.8% vs. 29.7%) injuries. In terms of body regions, e-scooter riders suffered from major injuries to the skull, facial cranium, cervical spine (43.8% e-scooter vs. 22.4% bicycle; p = 0.008) and less frequently to the trunk, thoracic and lumbar spine and pelvis (0.0% vs. 13.6%).

conclusionCompared to cyclists, injured e-scooter riders are younger, mostly do not wear a helmet and more often ride under the influence of alcohol. E-scooter accidents occur more frequently at night and the riders are more likely to suffer serious head injuries.
