Understanding the association between urban noise and nighttime light in China.
Article in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Nighttime light data partially reflects the process of urban modernization and its reaction to urban scale, but its correlation with noise remains unclear, especially over a long-term time series, remains unclear. To address this gap, we examine 31 provincial capital cities and municipalities in China as the study area, utilizing noise monitoring data and nighttime light data to explore their relationship in urban areas from 2012 to 2021. The results show that: (1) During the study period, the regional environmental noise and night light index of 31 major cities exhibited a consistent upward trend, with the average equivalent sound level of environmental noise in most urban areas fluctuating between 50.1 dB (A) and 60.0 dB (A). The overall quality evaluation was average, indicating that the effectiveness of noise pollution prevention and control was difficult to sustain in the long term. (2) The driving factor affecting the change in environmental noise quality in urban areas is population density. (3) There is a significant correlation between different types of noise proportion and urban construction and development, with the closest correlation observed with the urban economy, urban built-up area, and urban construction land area. Cities with high levels of urbanization tend to have more vulnerable acoustic environments. (4) Industrial noise percentage of urban environmental noise has a significant positive impact on nighttime light data. This study provides valuable insights for promoting the coordinated development between urbanization and acoustic environment optimization, as well as fostering a healthy and sustainable living environment.
