Analysis of the Dust-Concentration Distribution Law in an Open-Pit Mine and Its Influencing Factors.
Article in ACS omega, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
In this study, a solar-powered multipoint network monitoring method was used to record dust-particle concentrations and meteorological indicators in the Anjialing open-pit coal mine in the Pingshuo mining area. The factors influencing the concentrations of particulate matter of different maximum diameters (PM2.5, PM10, and total suspended particulates; TSPs) and the regularity of the spatial distribution were examined. The results show that the highest dust concentration and thus the most serious dust pollution occur in winter, and the lowest dust concentration is found in summer. There are peaks in dust concentration in December and January to February, and the pollution is more serious at these times. On a given day, the pollution is higher between 11:00 and 13:00, but it does not exceed the 24 h air concentration limits specified in the Chinese Ambient Air Quality Standard (GB3095-2012). It was found that the PM2.5 and PM10 concentrations are positively correlated with humidity and air pressure, and they are negatively correlated with wind speed, temperature, and noise. The TSP concentration is positively correlated with temperature and negatively correlated with humidity. The results of this study provide theoretical guidance and a reference for the distribution law of dust concentration in open-pit coal mines.
