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

introductionThe contribution of cerebrovascular hemodynamic disturbances to Alzheimer's disease (AD) remains unclear. Using time-shift analysis of blood-oxygenation-level-dependent (BOLD) signals, we explored associations between cerebral blood transit time, amyloid beta (Aβ) pathology, and cognition.

methodsWe included 131 non-demented individuals from the Alzheimer's Disease Neuroimaging Initiative. Three transit metrics - termed Lag

resultsAt baseline, prolonged Lag DISCUSSION: Prolonged blood transit time can reflect early vascular impairment in AD. HIGHLIGHTS: Vascular risks are associated with prolonged arterial transit time (Lag
