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

UbiG, an O-methyltransferase from the ubiquinone-biosynthesis pathway in Escherichia coli, catalyzes two O-methyl transfer steps. The primary structures of the O-methyltransferase enzyme family used in ubiquinone synthesis are conserved in both prokaryotes and eukaryotes, but their tertiary structures and catalytic mechanisms are not yet known. Here, UbiG with an N-terminal hexahistidine tag was expressed and crystallized. Crystals grown by the hanging-drop vapour-diffusion method diffracted to 2.00 Å resolution and belonged to space group C121, with unit-cell parameters a = 119.8, b = 58.6, c = 40.2 Å, β = 105.3°. Both Matthews coefficient analysis and the self-rotation function suggested the presence of one molecule per asymmetric unit in the crystal, with a solvent content of 50.52% (V(M) = 2.48 Å(3) Da(-1)).
