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

Organic radicals contain unpaired electrons and represent important open-shell systems for studying molecular spin effects and charge transport. However, conventional spectroscopic and magnetic measurements mainly yield signals, making it difficult to directly resolve intrinsic changes in orbital distribution, exchange interactions and spin state evolution. Single-molecule junctions address this limitation by translating local electronic and spin-related variations into measurable transport responses. In this perspective, we summarize the stable radical scaffolds and radical form tuning strategies relevant to single-molecule junctions. We then discuss how spin distribution, spin coupling and spin states govern orbital structure, molecule-electrode coupling and transport channels, and how these effects are read out electrically. Finally, we highlight opportunities in radical-electrode orbital hybridization, spin-selective transport, control of multiple spin states and radical-based single-molecule functional devices, with the aim of providing mechanistic guidance for molecular spintronic devices.
