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

Sulfated β-O4 lignin (SbO4L), a non-saccharide glycosaminoglycan mimetic, was recently disclosed as a novel exosite 2-directed thrombin inhibitor with the capability of mimicking sulfated tyrosine sequences of glycoprotein Ibα resulting in dual anticoagulant and antiplatelet activities. SbO4L engages essentially the same residues of exosite 2 as heparin and yet induces allosteric inhibition. Fluorescence spectroscopic studies indicate that SbO4L reduces access of the active site to molecular probes and affinity studies at varying salt concentrations show nearly 6 ionic interactions, similar to heparin, but much higher non-ionic contribution. The results suggest that subtle increase in non-electrostatic forces arising from SbO4L's aromatic scaffold appear to be critical for inducing allosteric dysfunction of thrombin's active site.
