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

The blood-brain barrier (BBB) is a specialized vascular structure that protects the brain micro-environment from toxins and pathogens in the blood. At the same time, the BBB presents a significant challenge for drug development, as it restricts the entry of most therapeutics into the brain. In this review, we first examine recent findings on the molecular and cellular architecture of the BBB, emphasizing the diverse mechanisms that facilitate the transport and exchange of molecules between the blood and the brain. We discuss current knowledge on the heterogeneity of the BBB along the arteriovenous axis and across different brain regions. Then, we explore the molecular and functional changes in the BBB that occur during normal ageing, neurodegeneration and acute brain injuries, and how prolonged BBB impairment affects transport mechanisms and disease progression. Additionally, we discuss novel developments in drug delivery strategies to transport small molecules, biologicals or cellular therapeutics across the BBB. Finally, we examine therapeutic opportunities to restore the BBB and discuss future directions in the field.
