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

Soda biscuit-like Ag-ZnO@ZIF-8 heterostructures were successfully synthesized using a secondary hydrothermal method for the first time, demonstrating exceptional ethylene glycol sensing performance. The sample (2-Methylimidazol (MeIm) concentration of 0.04 g) exhibits a remarkable response value of 1325.50 to 100 ppm ethylene glycol at 240 °C, along with a rapid response time of merely 7 s. Additionally, it displays outstanding gas selectivity (k = 28.63-696.90), great reproducibility and long-term stability. Further experiments indicate that the enhancement of the composite material's gas sensing performance can be primarily attributed to the interfacial electron transfer effect, the abundance of oxygen vacancies, and the synergistic interactions within the heterostructures. Overall, this study lays a solid theoretical foundation for the practical detection applications of ethylene glycol and provides new insights into the research on gas sensors based on ZnO-organic frameworks.
