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

Traumatic brain injury (TBI) contributes to morbidity in children, and more boys experience TBI. Cerebral autoregulation is impaired after TBI, contributing to poor outcome. Cerebral Perfusion Pressure (CPP) is often normalized by use of vasoactive agents to increase mean arterial pressure (MAP). In prior studies of newborn and juvenile pigs, vasoactive agent choice influenced outcome after TBI as a function of age and sex, with none protecting cerebral autoregulation in both ages and sexes. Dopamine (DA) prevents impairment of cerebral autoregulation in male and female newborn pigs via inhibition of upregulation of ERK mitogen activated protein kinase (MAPK) after fluid percussion injury (FPI). We investigated whether DA protects autoregulation and limits histopathology after FPI in juvenile pigs and the role of ERK in that outcome. Results show that DA protects autoregulation in both male and female juvenile pigs after FPI. Papaverine induced dilation was unchanged by FPI and DA. DA blunted ERK MAPK and prevented loss of neurons in CA1 and CA3 hippocampus of males and females after FPI. These data indicate that DA protects autoregulation and limits hippocampal neuronal cell necrosis via block of ERK after FPI in male and female juvenile pigs. Of the vasoactive agents prior investigated, including norepinephrine, epinephrine, and phenylephrine, DA is the only one demonstrated to improve outcome after TBI in both sexes and ages. These data suggest that DA should be considered as a first line treatment to protect cerebral autoregulation and promote cerebral outcomes in pediatric TBI irrespective of age and sex.
