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 hybrid networks containing metal coordination centers often disrupt continuous hydrogen-bonding pathways, limiting their intrinsic proton conductivity. Here we report a suite of hydrogen-bonded organic-inorganic frameworks (HOIFs) composed of ionic/neutral organic and metal-free inorganic building units that assemble into two- and three-dimensional hydrogen bonded networks through dense, multidirectional hydrogen bonds. These materials are nonporous and can be classified into three categories based on charge characteristics of their organic and inorganic components. They exhibit a rich structural diversity and unprecedented topologies such as the hoi net in HOIF-101. Systematic investigations show that they possess intrinsic superprotonic conductivity, with most of them achieving conductivity values >10
