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

A bioengineered heparin, as a replacement for animal-derived heparin, is under development that relies on the fermentative production of heparosan by Escherichia coli K5 and its subsequent chemoenzymatic modification using biosynthetic enzymes. A critical enzyme in this pathway is the mammalian 6-O-sulfotransferase (6-OST-1) which specifically sulfonates the glucosamine residue in a heparin precursor. This mammalian enzyme, previously cloned and expressed in E. coli, is required in kilogram amounts if an industrial process for bioengineered heparin is to be established. In this study, high cell density cultivation techniques were exploited to obtain recombinant 6-OST-1. Physiological studies were performed in shake flasks to establish optimized growth and production conditions. Induction strategies were tested in fed-batch experiments to improve yield and productivity. High cell density cultivation in 7-l culture, together with a coupled inducer strategy using isopropyl β-D-1-thiogalactopyranoside and galactose, afforded 482 mg l(-1) of enzyme with a biomass yield of 16.2 mg gcdw (-1) and a productivity of 10.5 mg l(-1) h(-1).
