Case analysis and finite element analysis of adult head skull fractures in people run over by motor vehicles.

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
The cranial stress distribution and morphological characteristics of cranial fractures in adult heads run over by motor vehicle were investigated. Cases of adults' heads run over by motor vehicles were collected. The skull fracture degrees are categorized into no skull fracture, multiple skull fractures, and skull fractures with brain tissue overflow. According to China's road traffic management system, vehicles in traffic accidents are categorized as heavy vehicles (weight ≥ 12 t), medium vehicles (4.5 t ≤weight < 12 t), light vehicles (1.8 t <weight < 4.5 t), and light minicars (weight ≤ 1.8 t). Finite element simulations were used to analyze the relationship between cranial fracture morphology and vehicle weight as well as cranial stress response. A total of 41 cases of heads run over by motor vehicles were collected. In seven cases of multiple skull fractures caused by medium vehicles, there were skull fractures on both the ground side and the tyre side, and the degree of skull fracture was more serious on the ground side than on the tyre side. Finite element simulations showed that the cranial stress in was more concentrated on the ground side than on the tyre side. Light vehicles and light minicars running over a head usually do not fracture the skull. Head injuries caused by medium vehicles are mainly characterized by multiple skull fractures, and the degree of skull fracture is more serious on the ground side than on the tyre side.
