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

In this work, a systematic synthesis of π-extended phenazine diimide derivatives is reported along with an extensive characterization of the optoelectronic properties of these molecules. The synthetic approach, based on the functionalization of naphthalene imide derivatives, enables both the direct synthesis of phenazine diimides and the preparation of phenazine dianhydride, thus resulting in a great synthetic versatility. Also, a comprehensive computational and spectroscopic characterization of the closed-shell reduced forms of phenazine diimides was carried out. The results indicate the differential formation of a dihydrophenazine or of an uncommon Meisenheimer complex, depending on the reduction conditions. These results highlight the great importance of structural design and reaction conditions in determining the nature of the reduced form of organic molecules, with important implications for the applications of these species as reagents and catalysts.
