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

backgroundHead and face injuries are the second most frequently reported injuries among bicyclists. Recently, helmet usage has increased, and in some countries, helmet laws have been introduced. However, subsequent changes in the incidence and severity of traumatic brain injury (TBI) are unknown, and data on neurosurgical interventions are lacking. Therefore, we analyzed a cohort of bicyclists with TBI, in a state with an enforced helmet law, and compared our results with the available literature.

methodsPatient data of bicycle accidents that occurred between January 2008 and January 2015 were extracted from the state trauma registry, and the corresponding patient files and CT scans were comprehensively reviewed.

resultsOf the 1019 patients admitted due to bicycle accidents, 187 patients suffered from TBI. Most cases were mild; however, 72 involved intracranial hemorrhages. Of the TBI patients, 113 were wearing helmets. CT scans were performed on 168 TBI patients, 120 of whom had a Rotterdam CT score of 1, with no difference between helmeted and non-helmeted patients. Open head injury (p < 0.05) and epidural hematomas were significantly less frequent among helmet wearers (p = 0.03). Ten patients required surgery; helmet use and neurosurgical involvement were not significantly correlated.

conclusionsPatients who wore helmets were significantly less likely to suffer from epidural hematomas and open head injuries. While TBI severity was not significantly different between helmeted and non-helmeted bicyclists, the overall occurrence of TBI and moderate to severe TBI among all admissions was lower than that seen in comparable studies from countries without helmet laws.
