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.
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
To clarify the influence of blast-induced seismic wave characteristics due to borehole coupling medium changes is an important guiding significance for blast vibration control. The energy calculation method of blasting seismic wave was derived and the influence of blasting source factors on seismic wave spectral characteristics was investigated. Then, the energy, composition and attenuation difference of seismic wave induced by explosive blasting with different coupling medium were compared and analyzed. Finally, experiments were carried out to verify analysis. The results show that the energy of blasting seismic wave is related to coupling medium, and the energy of water-coupled blasting induced seismic wave is higher than that of air-coupled blasting. The difference of seismic wave energy between water-coupled blasting and air-coupled blasting is not constant and influenced by rock, explosive categories and decoupling charge coefficient. The existence of water makes seismic wave have richer low-frequency components, and the main frequency is also lower than that of air-coupled blasting. In the process of propagation, air-coupled blasting attenuates faster, and the energy difference of seismic wave between water-coupled blasting and air-coupled blasting increases exponentially with propagation distance increase. The research results can provide reference for the safety control of water-rich rock blasting.
