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

This overview attempts to cover, from a personal viewpoint, the development of the 'heparin' field during the last four decades. In particular, it emphasizes the metamorphosis of heparan sulfate (HS), from a disturbing contaminant in heparin production to the present-day key player in cell and developmental biology. Our understanding of the structural properties of the polysaccharides has been greatly promoted by studies of their biosynthesis. We now have a fairly detailed view of the various enzymatic reactions, that convert the initial [4GlcAbeta1-4GlcNAcalpha1-]n polymer into sulfated products with highly variable proportions of GlcA/IdoA and of N-acetyl, N-sulfate and O-sulfate substituents. It is also recognized that the variously substituted domains of the polysaccharide serve to interact, in more or less specific fashion, with a multitude of proteins, and that these interactions are essential to the biological functions of the proteins. Molecular genetics has unravelled the gene structures for almost all of the enzymes required to synthesize a heparin or HS chain, and has shown that several of these proteins exhibit genetic polymorphism. While differences in substrate specificity between enzyme isoforms may help to explain the structural variability of, in particular, HS chains, we still only partly understand the key features of heparin/HS biosynthesis and its regulation.
