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

We have computationally studied the aromatic nature of molecules built from tetraoxa-isophlorin (TOI) and Ni(ii)-norcorrole (NiNc) moieties. Calculations of the magnetically induced current density (MICD) susceptibility and magnetically induced ring currents (MIRC) show that antiaromatic porphyrinoids form bound aromatic stacked dimers with a distance of about 3 Å between the monomers. We design molecules consisting of many antiaromatic rings because they bind stronger due to the aromatic stabilization and a formal double bond between the individual pairs of the molecular rings of the stacked dimers. Global conjugation and strong coupling between the antiaromatic moieties can be prevented by introducing linkers with formal single bonds between the antiaromatic rings.
