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 new cyclic pentasaccharide comprising an oxymethylene glycosidic bond connecting the individual α-d-glycopyranoside monomers is synthesized through cycloglycosylation of a linear pentasaccharide precursor, which, in turn, is synthesized through the block glycosylation method. Molecular modeling shows that the 30-membered macrocyclic pentasaccharide is a distorted ellipsoid structure, with the lower and upper rims occupied by secondary and primary hydroxyl groups, respectively. Following the synthesis, the microenvironment of the cyclic pentasaccharide is assessed through thermodynamic evaluation upon complexation with 1-aminoadamantane in an aqueous solution, which shows the formation of ∼1:2 host-to-guest complex and a binding affinity of 10 500 (±425) M
