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

Enolase is a glycolytic enzyme that catalyzes the interconversion of phosphoenolpyruvate and 2-phosphoglycerate. In order to gain insight into the biological significance of the oligomeric state of this enzyme, the putative enolase MJ0232 from the hyperthermophilic archaeon Methanococcus jannaschii was cloned, overexpressed and purified. Crystals were obtained by the oil-microbatch method at 291 K using PEG 4000 as a precipitant. A native data set was collected to 1.85 A resolution. The crystal belonged to the tetragonal space group I4, with unit-cell parameters a = 148.8, c = 91.2 A. An initial model was obtained by molecular replacement, which revealed an octameric subunit association (a tetramer of dimers). This result is consistent with that from a dynamic light-scattering experiment, suggesting biological relevance of the octameric state of MJ0232 in solution.
