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

Fructose-1,6-diphosphate (FDP), an intracellular metabolite of glucose, has anticonvulsant activity in several models of acute seizures in laboratory animals. The anticonvulsant effect of FDP is most likely due to a direct effect since intraperitoneal and oral administration results in significant increases in brain levels. A number of mechanisms have been proposed for this action of FDP. One possibility is that peripheral administration of FDP results in changes in brain metabolism that are anticonvulsant. Glucose can be metabolized through the glycolytic or pentose phosphate pathway. There is evidence that the pentose phosphate pathway is more active in the brain than in other tissues, and that, in the presence of elevated levels of FDP, the majority of glucose is metabolized by the pentose phosphate pathway. The pentose phosphate pathway generates NADPH, which is used to reduce glutathione. The reduced form of endogenous glutathione has been shown to have anticonvulsant activity. Taken together, the data suggest a hypothesis that exogenously administered FDP gets into the brain and astrocytes where it increases the flux of glucose through the pentose phosphate pathway, generating additional NADPH for the reduction of glutathione.
