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

introductionCerebrovascular lesions are associated with cognitive impairment. However, the impact of AD neuropathological changes (ADNC) on cerebral microvasculature is not completely understood.

methodsTwelve decedents with ADNC and 15 matched controls were selected from the Brain Bank. The changes in the median tunica and basement membrane-related extracellular matrix (ECM) contents of the microvasculature were quantified and compared. Additionally, we explored the related mechanisms of agrin in pericytes.

resultsVenular collagenosis was significantly more severe in AD patients (p < 0.001), and ECM remolding was significantly correlated with ADNC. In the AD group, blood-brain barrier (BBB) disruption and decreased pericytes were observed. Finally, we confirmed that agrin induced ferroptosis in pericytes and BBB disruption in vitro. DISCUSSION: Our data indicate that venular collagenosis and significant ECM remolding are important contributors to ADNC. The mechanism by which agrin's role in disrupting the BBB by inducing ferroptosis presents a potential new target. HIGHLIGHTS: Changes in the median tunica and basement membrane-related ECM contents of the microvasculature were quantified in human brains. Venular collagenosis was significantly more severe in AD patients. In the AD group, BBB disruption and ECM remodeling were important contributors to AD neuropathological changes. Agrin disrupted the BBB by inducing ferroptosis in pericytes, which presents a potential new target.
