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

Neuronal failure leading to dementia in neurodegenerative diseases is evidenced in vivo by functional and structural changes in the brain such as reductions of glucose consumption and volume of grey matter. The earliest phase of cognitive decline and presymptomatic stages of these diseases are heralded by specific patterns of hypometabolism, even in the absence of atrophy, which are currently considered as diagnostic biomarkers. Atrophy is less consistently found as an initial marker of these diseases and is invariably present in moderate to severe stages with a disease-related topography. The relationship between these two markers is not uniform, but in the two diseases in which they have been directly compared, Alzheimer's and Parkinson's disease, altered hypometabolism precedes and exceeds atrophy in most regions. This suggests a two-step degenerative process. In contrast to these findings, the hippocampus skips this pattern and is more structurally than functionally affected, thereby suggesting a different pathological mechanism in this particular area. More studies are needed to disentangle the mechanisms underlying both markers and their relationship in neurodegenerative diseases.
