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

Graphene nanoribbons (GNRs) with zigzag edges are promising materials for spintronic devices due to tunable bandgaps and spin-polarized edge states. Porphyrins offer complementary benefits such as desirable optoelectronic properties. Here we combine these features in a hybrid system by means of the on-surface synthesis of zigzag-edge GNRs embedded with porphyrins laterally fused along the ribbon backbone. Using scanning probe methods, we show that this design achieves strong electronic coupling between the porphyrin and the GNR. For transition metal porphyrins, pronounced exchange coupling between distant metal centres is mediated by the π-electron system. Such a hybrid d and π electron ribbon system introduces spin-orbit coupling and magnetic anisotropy to carbon nanomaterials, and holds great promise for coherent electrical control of electron spins.
