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

The first time in-depth characterization of dibenzoterrylene (DBT) was performed by a combination of various experimental and computational techniques. First structure confirmation and atom assignment were achieved by means of 2D-NMR and powder X-ray. DFT methods shed light on the conformational space of DBT and, more importantly, on the complex electronic structure of the molecule. DBT appears to be the first studied molecule, two low-lying conformers of which have drastically different biradical character. EPR and NMR studies show the effect of solvent on the population of the biradical state. This demonstrates the perspectives of the usage of DBT and its derivatives in spintronics and other quantum technologies.
