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

Conjugated organic molecules with open-shell diradical character (y) possess two weakly paired electron spins interacting across their constituent π-systems. These materials provide fundamental insight into the nature of electron pairing, enabling the utilization of the spin degree of freedom within emerging technologies. However, materials systems that synergistically offer high modularity, tunable y, high chemical stability, and interrelated (opto)electronic functionalities remain limited. Here, we report the facile synthesis of donor-acceptor-donor diradicaloids comprised of a central electron-deficient 6,7,8,9-tetrachloro-[1,2,5]thiadiazolo[3,4-b]phenazine acceptor flanked by electron-rich thiophene-based donors. Nuclear magnetic resonance and electron paramagnetic resonance spectroscopies, and theoretical investigations that account for the multiconfigurational nature of these species, connect a narrowing of the singlet-triplet splitting (∆E
