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) is one of the leading causes of death and disability, particularly amongst the young and the elderly. The functions of the blood-brain barrier (BBB) and blood-cerebrospinal fluid barrier (BCSFB) are strongly impaired after TBI, thus affecting brain homeostasis. Following the primary mechanical injury that characterizes TBI, a secondary injury develops over time, including events such as edema formation, oxidative stress, neuroinflammation, and alterations in paracelullar and transcellular transport. To date, most therapeutic interventions for TBI have aimed at direct neuroprotection during the acute phase and have not been successful. Targeting the barriers of the central nervous system (CNS) could be a wider therapeutic approach, given that restoration of brain homeostasis would benefit all brain cells, including neurons. Importantly, BBB disregulation has been observed even years after TBI, concomitantly with neurological and psychosocial sequelae; however, treatments targeting the post-acute phase are scarce. Here, we review the mechanisms of primary and secondary injury of CNS barriers, the accumulating evidence showing long-term damage to these structures and some of the therapies that have targeted these mechanisms. Finally, we discuss how the injury characteristics (hemorrhagic vs non-hemorrhagic, involvement of head rotation, gray vs white matter), the sex, and the age of the patient need to be carefully considered to improve clinical trial design and outcome interpretation, and to improve future drug development.
