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

objectiveThis study was undertaken to investigate the mechanisms underlying the paradoxical phenomena of excessive neurotransmitter release and suppressed sodium-spike generation due to depolarization block (DB) during seizure activity.

methodsWe employed acute neocortical slices from mice to investigate DB in pyramidal cells (PCs) during epileptiform activity (EA). Local high-K

resultsMembrane potential levels of DB in PCs during EA remained constant even with strong hyperpolarization, suggesting dependence on an ionic reversal potential. Local high-K SIGNIFICANCE: Our findings demonstrate that, during epileptiform activity, DB is predominantly determined by excessive accumulation of extracellular K
