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

Chrysene-based nanographenes (ChrNGs), despite their relatively small structures, have been reported to exhibit low highest occupied molecular orbital (HOMO)-lowest unoccupied molecular orbital (LUMO) energy gaps and strong long-wavelength fluorescence, making them attractive for various applications. However, the precise synthesis of ChrNGs remains challenging, and their availability is limited compared with other classes of nanographenes. Herein, we report the synthesis of novel ChrNGs by a successive annulative π-extension (APEX) reaction. Using diphenylacetylene and benzonaphthosilole in a Pd/
