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 fluoranthene motif combines a planar geometry with electron-deficient character, rendering fluoranthene and its larger congeners like indenofluoranthene suitable compounds for designing n-semiconducting materials for applications in organic electronics. However, examples in which their opto- and electrochemical properties are tuned through selective five- or six-membered ring annelation, as well as by isosteric nitrogen substitution of a C-H unit within the fluoranthene core, remain scarce. Here the structure-property-relationships of a series of aza-fluoranthene-derived constitutional isomers as well as their syntheses by selective Pd-catalyzed indeno- or benzannelation of the same precursor is described.
