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

Crystalline materials that exhibit attractive mechanical responses under external stresses have attracted considerable interest due to their potential applications across multiple fields. Here, we present a crystalline form of 9-fluorenone hydrazone (9-FH) that exhibits dual mechanical stress response, that is, plasticity and elastoplastic behavior, on different crystallographic faces. This dual mechanical response arises from specific molecular packing features, wherein intermolecular interactions play a key role in modulating the crystal's mechanical properties from the different faces. Here, large 9-FH single crystals demonstrate excellent plastic behavior under applied forces, attributed to the reorganization of weak interactions across the slip planes. Moreover, this comprehensive analysis offers detailed insights into the distinct mechanical responses of 9-FH and the underlying mechanism.
