Dynamics of brain connectivity across the Alzheimer's disease spectrum through magnetoencephalography.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Changes in static functional connectivity have been extensively linked to Alzheimer's Disease (AD), however, dynamic functional connectivity (dFC) across the AD continuum remains understudied. The current investigation leverages the high temporal resolution of MEG to dissect the dynamics of brain connectivity alterations across various stages of AD and their association with cognitive decline and structural brain changes. 321 participants were included, categorized into healthy control, subjective cognitive decline (SCD), and mild cognitive impairment (MCI) groups. Amplitude envelope correlation with leakage correction was calculated over MEG signals using a sliding window, and the correlation across epochs was studied to assess dFC. We explored dFC associations with cognitive scores, grey matter volume, and white matter fractal anisotropy. Whole-brain dFC declined along the AD continuum, especially in the alpha and beta bands, with pronounced reductions in the frontal and temporal lobes and default mode network regions. Moreover, these dFC changes correlated with cognitive decline and structural brain alterations. The present study underscores the relevance of dFC in capturing early temporal dynamic alterations, linking high-frequency activity in association cortices to white matter integrity and cognitive deterioration, thus highlighting the metric's potential as a sensitive marker of disease progression.
