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

We conducted a review of the electrophysiological manifestations of Alzheimer's disease (AD) as captured by electroencephalography (EEG) and magnetoencephalography (MEG), with a focus on tracking their evolution through disease progression. To link electrophysiological features to the underlying neurobiology of AD, we prioritized studies that integrated EEG/MEG with other data modalities, such as positron emission tomography (PET) imaging and/or fluid biomarkers (cerebrospinal fluid [CSF] or blood/plasma) of amyloid beta (Aβ) and tau. Our analysis contextualizes these findings within current mechanistic hypotheses of AD pathophysiology. A key highlight of the present review is that electrophysiological changes along the AD disease progression may follow a non-monotonic trajectory, underscoring a need for caution when developing biomarkers for early detection or staging the disease with non-invasive electrophysiology. We also discuss outstanding challenges in the interplay between AD pathology and electrophysiological dynamics. This review highlights the potential of multimodal approaches to refining our understanding of AD and improving its early diagnosis. HIGHLIGHTS: A systematic review of electrophysiological signatures of AD in multimodal studies. Existing findings are contextualized with AD pathophysiology and neurobiology. Electrophysiological signatures of AD evolve in a dynamic, non-linear fashion.
