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

Inositol is an essential metabolite required for membrane biogenesis, cell signaling and trafficking, and gene expression. Its importance is underscored by the fact that inositol depletion leads to death in eukaryotic cells ranging from yeast to human. Perturbation of inositol homeostasis is implicated in numerous human disorders. In yeast, inositol is synthesized de novo from glucose-6-phosphate (G-6-P) through a two-step pathway controlled by the rate-limiting enzyme myo-inositol phosphate synthase (MIPS), encoded by INO1. INO1 expression is tightly controlled by the Henry regulatory circuit in response to inositol and by the Reg1-Snf1 pathway in response to glucose. As both inositol synthesis and glycolysis utilize the same precursor, G-6-P, the current study tested the hypothesis that inositol synthesis is regulated by glycolytic activity. Genetic and pharmacological approaches were used to alter glycolysis. Inositol synthesis was determined by liquid chromatography mass spectrometry analysis of [U-
