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

The enzyme 2-keto-3-deoxy-9-O-phosphonononic acid phosphatase (KDN9P phosphatase) functions in the pathway for the production of 2-keto-3-deoxy-D-glycero-D-galacto-nononic acid, a sialic acid that is important for the survival of commensal bacteria in the human intestine. The enzyme is a member of the haloalkanoate dehalogenase superfamily and represents a good model for the active-site protonation state of family members. Crystals of approximate dimensions 1.5 × 1.0 × 1.0 mm were obtained in space group P2(1)2(1)2, with unit-cell parameters a = 83.1, b = 108.9, c = 75.7 Å. A complete neutron data set was collected from a medium-sized H/D-exchanged crystal at BIODIFF at the Heinz Maier-Leibnitz Zentrum (MLZ), Garching, Germany in 18 d. Initial refinement to 2.3 Å resolution using only neutron data showed significant density for catalytically important residues.
