Regional cerebral blood flow reflects both neurodegeneration and microvascular integrity across the Alzheimer's continuum.

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
introductionAlzheimer's disease (AD) typically involves both neurodegenerative and vascular pathologies, each associated with reductions in cerebral blood flow (CBF). However, it remains unclear whether vascular and neural contributions to regional CBF can be differentiated.
methodsUsing 3D background-suppressed arterial spin labeled perfusion magnetic resonance imaging, we evaluated regional CBF in a cohort of 257 participants across the AD continuum and assessed the impact of risk factors for both AD and small vessel disease (SVD) on regional CBF.
resultsVascular risk factors (VRFs) were associated with reduced CBF in normal-appearing periventricular white matter, while amyloid positivity was associated with reduced CBF in the posterior cingulate cortex and precuneus. Putative SVD-sensitive regions in white matter exhibited diagnosis-related CBF changes comparable to those in typical AD cortical regions. DISCUSSION: Spatial patterns of hypoperfusion may differentiate AD and VRF-related effects on regional CBF. Our findings also support the contribution of SVD in AD pathogenesis. HIGHLIGHTS: We used 3D background-suppressed pCASL MRI to evaluate CBF across the AD continuum. Putative SVD-sensitive regions in white matter exhibited diagnosis-related CBF changes. AD and/or SVD risk correlated with reduced CBF in AD and/or SVD-related regions. VRFs were associated with more widespread CBF reductions than amyloid positivity. Spatial patterns of hypoperfusion may differentiate AD and VRF-related effects.
