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

Hydrogen-bonded organic frameworks (HOFs) are promising porous materials, yet their development is hindered by an inherent trade-off between structural stability and functional site accessibility. Conventional stabilization strategies relying on extensive π-π stacking inevitably shield aromatic surfaces, compromising adsorption performance. Herein, we report a synergistic design strategy that integrates high hydrogen-bonding connectivity with inherently nonplanar molecular conformations to overcome this challenge. The strategically designed tetraisophthalate linker, featuring a hexamethylbiphenyl core, adopts a nonplanar conformation that suppresses extended π-π stacking, while its eight carboxylic acid groups form a dense hydrogen-bonded network ensuring framework robustness. The resulting HOF-ZJNU-10 exhibits a high BET surface area (2500 m
