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

introductionWhite matter (WM) is affected by and serves as a pathway to neurofibrillary tangle (NFT) propagation in Alzheimer's disease (AD). Cerebral amyloid angiopathy (CAA) associates with neuritic plaques (NPs) to exacerbate NFT accumulation. We aim to study how these co-pathologies affect WM integrity.

methodsWe performed a cross-sectional study of ante mortem diffusion tensor imaging (DTI) data according to participants' post mortem NFT, NP, and CAA neuropathology, from the National Alzheimer's Coordinating Center dataset.

resultsWe found asymmetric DTI changes in several WM regions between Braak NFT stages II and IV and V/VI, and across CAA pathological burden, with increased mean, radial, and axial diffusivities. CAA-NFT co-pathology effects were observed mainly in the splenium of the corpus callosum. DTI metrics were associated with cognitive function and hippocampal volumes. DISCUSSION: Our results suggest that WM integrity is differentially impacted by AD neuropathology, with CAA and NFTs influencing each other's effects on WM microstructure. HIGHLIGHTS: Diffusion tensor imaging (DTI) changes were observed in several white matter (WM) regions between advanced Braak stages and across cerebral amyloid angiopathy (CAA). CAA demonstrated a greater WM impact on the right hemisphere, while neurofibrillary tangles (NFTs) had greater impact on the left. CAA-NFT concurrent effects were mainly noticed in the splenium of the corpus callosum. WM DTI metrics were associated with cognition and hippocampal volumes.
