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

Neurofibrillary tangles, formed of misfolded, hyperphosphorylated tau protein, are a pathological hallmark of several neurodegenerations, including Alzheimer's disease. Tau pathology spreads between neurons and propagates misfolding in a prion-like manner throughout connected neuronal circuits. Tauopathy is accompanied by significant neuronal death, but the relationships between initial tau misfolding, propagation across connected neurons and cytotoxicity remain unclear. In particular the immediate functional consequence of tau misfolding for the individual neuron is not well understood. Here, using microfluidic devices to recreate discretely organized neuronal connections, we show that the spread and propagation of misfolded tau between individual murine neurons is rapid and efficient; it occurs within days. The neurons containing and propagating tau pathology display selective axonal transport deficits but remain viable and electrically competent. Therefore, we demonstrate that seed-competent misfolded tau species do not acutely cause cell death, but instead initiate discrete cellular dysfunctions.
