Plasma biomarker-informed brain topology for cognitive resilience: applications in non-pharmacological interventions concerning cognitive aging.
Article in Alzheimer's & dementia (Amsterdam, Netherlands). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionIn the context of non-pharmacological interventions (NPIs), cognitive resilience refers to the capacity to enhance cognition from NPIs in the presence of neurodegeneration, and it is closely linked to brain network topological characteristics. This study aims to examine the roles of plasma biomarkers and brain topology in NPI-related cognitive resilience by developing a plasma biomarker-informed brain topology for cognitive resilience (PBIT-CR) index.
methodsWe first identified latent brain topology components from brain topological features by associating them with five plasma biomarkers in a predefined discovery sample and then evaluated and validated the interaction between these latent components and baseline neurodegeneration in two additional samples.
resultsOne brain topology component informed by plasma biomarkers, which indicates greater neuroprotection, interacted with baseline neurodegeneration to predict cognitive enhancement following two distinct NPIs. DISCUSSION: Baseline brain topological characteristics informed by plasma information could provide insights for identifying individuals who may benefit from NPIs.
