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

Accumulation in the brain of metabolic waste products such as amyloid-β and hyperphosporylated tau (tau) is a hallmark of dementia (e.g., Alzheimer's disease). One possible underlying mechanism is impaired cerebral paravascular (glymphatic) clearance of toxic solutes. Recently, we have provided evidence of glymphatic circulation being present in the human brain, utilizing repeated magnetic resonance imaging (MRI) acquisitions before/after intrathecal injection of an MRI contrast agent, serving as a cerebrospinal fluid (CSF) tracer (glymphatic MRI [gMRI]). In a recent study, we utilized the same methodology to assess glymphatic clearance function within an anatomical region that has a key role in cognitive function-the entorhinal cortex (ERC). gMRI was compared in individuals with the dementia subtype idiopathic normal pressure hydrocephalus (iNPH;
