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

Stroke is the leading cause of permanent disability and death in the world. The therapy for acute stroke is still limited due to the complex mechanisms underlying stroke-induced neuronal death. The generation of a 17-kDa neurotoxic tau fragment was reported in Alzheimer's disease but it has not been well studied in stroke. In this study, we observed the accumulation of 17-kDa tau fragment in cultured primary neurons and media after oxygen-glucose deprivation/reperfusion (OGD/R) treatment that could be diminished by the presence of a calpain inhibitor. This calpain-mediated proteolytic tau fragment was also detected in brain tissues from middle cerebral artery occlusion-injured rats and acute ischemic stroke patients receiving strokectomy, and human plasma samples collected within 48 h after the onset of stroke. The mass spectrometry analysis of this 17-kDa fragment identified 2 peptide sequences containing 195-224 amino acids of tau, which agrees with the previously reported tau
