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

Chirality-induced spin effects, first observed in hybrid interface structures, are distinguished by their remarkable robustness. For practical applications and tunability, chemically modular design concepts are particularly promising. Here, we demonstrate chirality-induced spin selectivity (CISS) in sub-3 nm metal oxido nanoclusters, using bismuth-based systems as a model platform that can be selectively activated by chiral carboxylate ligands. While both chiral and achiral nanoclusters adsorb similarly onto magnetic Au/Co/Au nanostructures via sulfur-metal bonding, the adsorption process alone does not induce a CISS effect, i.e., not imparting chirality to the interface. Our findings establish a modular molecular design strategy that enables the targeted functionalization of chiral metal oxido nanoclusters, opening perspectives for their integration into spin-dependent applications, including optoelectronic systems.
