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

Non-stoichiometric multicomponent crystals have the potential not only to fine-tune material properties but also to emerge new functionalities. In this paper, the composition-dependent dynamic transformation of non-stoichiometric cocrystalline hydrogen-bonded organic frameworks (NS-HOFs) composed of tetrakis(4-carboxyphenyl)hexahydropyrene and -pyrene derivatives (CP-Hp and CP-Py, respectively) is reported. Isostructural mono-component frameworks of CP-Hp and CP-Py (CP-Hp-1 and CP-Py-1, respectively) underwent structural transformation into the corresponding shrunk frameworks (CP-Hp-2 and CP-Py-2, respectively) by spontaneous release of the included solvent molecules, where the transformation speed of CP-Hp-1 is faster than that of CP-Py-1. NS-HOFs of CP-Hp and CP-Py, denoted by CP-HpPy-1(x), where x is the mixing ratio of CP-Hp, show the transformation into CP-HpPy-2(x), and the transformation behaviors strongly depend on the composition ratio. Interestingly, the transformation speed is not proportional to the composition ratio, while the maximum speed is observed for CP-HpPy-1(0.5). This is, to the best of these knowledge, the first example of composition-dependent structural changes in non-stoichiometric cocrystalline frameworks, demonstrating that dynamic behaviors can be modulated nonlinearly by the composition of the frameworks and shedding light on new aspects of porous soft crystals.
