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

Experimental measurements often show significant variations in gas adsorption on aluminosilicate zeolites, thereby inducing considerable uncertainty in the gas separation and storage performance. These variations are largely attributed to the distribution of aluminum (Al) atoms within the zeolite framework. It is challenging to experimentally control the distribution of Al atoms during zeolite synthesis. The vast number of plausible Al-substituted configurations also makes it difficult to estimate the overall range of adsorption. To resolve this, we deploy a new representation of crystallographic frameworks using single repeating units (SRU). An SRU consists of the smallest network of tetrahedral atoms that can be repeated as a single building block to represent an entire zeolite framework. SRUs enable a selective enumeration of unique Al-substituted configurations, thereby leading to an efficient computational framework for quantifying the variations in equilibrium gas adsorption on Al-substituted zeolites without an exhaustive search. We apply this technique to analyze CO
