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

Robust external manipulation of spin communication in molecular frameworks is desirable for potential applications in quantum information science. Herein, we incorporate two types of dithienylethene (DTE) units into tris(2,4,6-trichlorophenyl)methyl (TTM)-based diradicaloids and report on the successful bistable switching of the optical and magnetic properties of the molecule. Visible-light irradiation of the open form generates up to 97% of the closed form, in which conjugation between the two radical centers leads to absorption over the entire visible range of the spectrum as well as a twofold increase of the singlet-triplet gap. These results establish TTM/DTE hybrids as persistent and multi-level responsive diradicaloids.
