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

Separating perfluorinated cyclopropane/propane mixtures is critical yet challenging for sustainably producing high-purity perfluropropane in the advanced electronics industry. Conventional one-step adsorption separation methods lack proper selectivity due to similar molecular sizes and properties. We introduce a tandem reaction-adsorption approach with ultrahigh selectivity and low-pressure uptake. The initial step converts perfluorinated cyclopropane into olefins, enhancing molecular size and polarity differences and enabling efficient sieving using a scalable, stable molecular sieve developed. The method achieves selectivity over two orders of magnitude higher than conventional methods, producing 99.9999% pure perfluropropane at 12.5 liters per kilogram per hour with a 98.8% yield in the fixed beds. The tandem reaction-adsorption methodology introduces an efficient route for separating and purifying industrially challenging gas analogs.
