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 an intense depolarization wave implicated in brain injury. In focal ischemia, recurrent peri-infarct depolarization (PID) waves akin to SD worsen the ischemic injury by exacerbating the blood flow-metabolism mismatch. We recently showed that gabapentin suppresses SD. We, therefore, tested gabapentin on PIDs and stroke outcome. Gabapentin pretreatment (200  mg/kg, intravenously) reduced the infarct volume by 23% after transient focal ischemia in mice. However, the frequency and duration of PIDs were not suppressed when recorded for 2  hours during ischemia, suggesting that gabapentin reduces infarct volume independent of PID suppression.
