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 a modifiable risk factor for Alzheimer's disease (AD). TBI and AD share several histopathological hallmarks: namely, beta-amyloid aggregation, tau hyperphosphorylation, and plasma protein infiltration. The relative contributions of these proteinopathies and their interplay in the pathogenesis of both conditions remains unclear although important differences are emerging. This review synthesises emerging evidence for the critical role of the neurovascular unit in mediating protein accumulation and neurotoxicity in both TBI and AD. We propose a shared pathogenic cascade centred on a neurovascular unit, in which increased blood-brain barrier permeability induces a series of noxious mechanisms leading to neuronal loss, synaptic dysfunction and ultimately cognitive dysfunction in both conditions. We explore the application of this hypothesis to outstanding research questions and potential treatments for TBI and AD, as well as other neurodegenerative and neuroinflammatory conditions. Limitations of this hypothesis, including the challenges of establishing a causal relationship between neurovascular damage and proteinopathies, are also discussed.
