Contrasting patterns of leptomeningeal and parenchymal gadolinium extravasation in cerebral amyloid angiopathy: An MRI-based evaluation.

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.
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
backgroundPrevious studies suggest that blood-brain barrier (BBB) disruption may play a role in the pathophysiology of vessel rupture in cerebral amyloid angiopathy (CAA). Here, in a cross-sectional cohort study, we apply contrast-enhanced 3 Tesla magnetic resonance imaging (MRI) to test the hypothesis that the BBB is damaged in patients with CAA and to determine whether BBB leakage is associated with hemorrhagic brain injury in CAA.
methodsParenchymal BBB leakage rate (K
resultsIn total, 25 patients with a clinical diagnosis of probable CAA without prior intracerebral hemorrhage and 19 age- and sex-matched controls were included. In patients with CAA, BBB leakage rates were lower in the cortex (4.2 × 10 DISCUSSION: Our results suggest that global parenchymal gadolinium extravasation across the BBB is lower in patients with CAA compared with controls. This observation can be explained in terms of limited capillary blood perfusion and/or raising the possibility that vascular amyloid-β deposition impairing molecular transport across the BBB. In contrast, focal leptomeningeal enhancement was higher in CAA, reflecting vessel wall infiltration.
