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

Spreading depression (SD) is a slowly propagating wave of transient neuronal and glial depolarization that develops after stroke, trauma and subarachnoid hemorrhage. In compromised tissue, repetitive SD-like injury depolarizations reduce tissue viability by worsening the mismatch between blood flow and metabolism. Although the mechanism remains unknown, SDs show delayed electrophysiological recovery within the ischemic penumbra. Here, we tested the hypothesis that the recovery rate of SD can be varied by modulating tissue perfusion pressure and oxygenation. Systemic blood pressure and arterial pO(2) were simultaneously manipulated in anesthetized rats under full physiologic monitoring. We found that arterial hypotension doubled the SD duration, whereas hypertension reduced it by a third compared with normoxic normotensive rats. Hyperoxia failed to shorten the prolonged SD durations in hypotensive rats, despite restoring tissue pO(2). Indeed, varying arterial pO(2) (40 to 400 mm Hg) alone did not significantly influence SD duration, whereas blood pressure (40 to 160 mm Hg) was inversely related to SD duration in compromised tissue. These data suggest that cerebral perfusion pressure is a critical determinant of SD duration independent of tissue oxygenation over a wide range of arterial pO(2) levels, and that hypotension may be detrimental in stroke and subarachnoid hemorrhage, where SD-like injury depolarizations have been observed.
